Has no effect when the last position is 1 + a multiple of xtstep. Default is to use the tick.last attribute of the state sequence object.
seqformat():
For from = "SPELL" and process = FALSE, pdata = "auto" is now equivalent to NULL instead of raising an error. Also, using argument pvar with pdata = NULL now raises a warning instead of an error and pvar is simply ignored.
For from = "SPELL" an error is raised when columns referred to
by begin and end are of class "Date".

Declaring use of C++11 for log1p: SystemRequirements: C++11 declaration
in DESCRIPTION and math.h header in NMSdistance.cpp
Internal function checkargs() renamed as TraMineR.check.depr.args()
and made public for use in TraMineRextras.
alphabet(): the get form now also applies to event sequences.
In addition, an error is now raised when the argument is not a state sequence object, an event sequence object, or a probabilistic suffix tree (see the PST package for the latter).
seqdecomp(): the miss argument can now also be a vector, e.g. miss = c("*", "%")
seqformat() has a new right argument to be used with
to = 'SPELL'. The default right = 'DEL' suppresses the end spells of missing values. Set right = NA to keep the end spells of missing values.
seqdef() now raises an error message when void is not a character different from left, gaps, and right.
seqtrate() gains a new argument count. When count = TRUE, the function returns counts of transitions instead of transition probabilities.
seqpcplot():
Due to a change in the R tapply function, option ltype="non-embeddable" did no longer work.
seqefsub() with non-null str.subseq argument:
multiple partial matches between events in str.subseq and the alphabet of events of
the eseq event sequence object crashed the R session. Fixed by a change in the internal seqecreatesub function.
seqformat(): to="TSE" and to="SPELL" produced errors or unexpected results in presence of missing and/or void states. Now, when to = "SPELL", the missing and void codes are both converted to NA before conversion while they are kept as is when to = "TSE".
seqetm() produced an error in presence of void elements.
An error occurred in the internal implicativestat function when a same condition subsequence was present in all subsequences.
Documentation of seqformat() and seqecreate(): added examples of the handling of missings in conversion into TSE and SPELL format.
seqformat():
Redesigned version of the function with a new extensible, robust and documented implementation.
Rewritten documentation with argument types, default values, scopes and detailed explanations.
Added and generalized conversion to "SPELL" from TraMineRextras;
added a with.missing argument specifically for this conversion.
Added the possibility to pass directly the unique individual IDs (row names)
of the input sequences with id when converting to "TSE".
Clarified the meaning of the id argument and changed its position in the
list of arguments to reflect this.
Changed the default value of the id, begin, end, and
status arguments (now "SPELL" oriented).
Renamed compressed argument as compress to avoid
confusion (here it applies to the output, not to input data).
Renamed nr argument as missing to avoid confusion (here
it specifies the code to consider as missing values in input data,
which is not the TraMineR internal code for missing values in state
sequence objects).
Adapted function calls to match the renamed argument names
(compressed, nr) and the new input type checking (ie.
single strings are deprecated).
See the updated documentation of seqformat() for details.
SPS_to_STS(): renamed nr argument as missing to match
seqformat() argument names renaming.
seqformat():
From "SPELL" to "TSE": output IDs were incorrect.
From "SPELL" to "STS": states not appearing in the
data were dropped from the output column levels.

white space insertion.
is.positive.integers(): check if an object is a vector of
positive integers.
is.a.character(): check if an object is a (unique) character.
is.a.string(): check if an object is a string.
is.strings(): check if an object is a vector of strings.
is.index(): check if an object is a positive integer or a string.
is.indexes(): check if an object is a vector of positive integers
or strings.
checkindex(): check if an object is a valid data frame or matrix
index; otherwise, an error is raised and an information message is
displayed.
checkindexes(): check if an object is a vector of valid data
frame or matrix indexes; otherwise, an error is raised and an information
message is displayed.
Grouped internal is.xxx helper functions into a single
TraMineR-is_helpers.R file.
Generalized msg.warn() / msg.warn0() and msg() /
msg0() code.
Internal C/C++ function tmrWeightedInertiaDist() made public as the R function TraMineRInternalWeightedInertiaDist(). (Used by package Weightedcluster)
This is a major update of the CRAN version of TraMineR.
Check also changes in versions 1.9-14, 2.0-0, 2.0-1, 2.0-2, 2.0-3, and 2.0-4 that have not been released on the CRAN.
seqtrate(): now accepts a sequence object (seqdata argument) containing only one sequence.
seqdist(): now accepts a reference sequence object (refseq argument)
containing missing values while the main sequence object (seqdata argument) doesn't.
Replaced default deprecated values of norm in
seqdistmc() and seqtree().
Fixed issues with examples in documentation page of
seqtree().
Renamed several argument names to increase consistency within TraMineR and
between TraMineR and R. The aim is also to have a common naming
convention within TraMineR.
A new internal function (checkargs())is used to guarantee
backward compatibility. If the old argument name is used instead of the new
one, a warning message with an explanation is displayed and the execution
continues. If the new and old argument names are used together, an error
message is displayed and the execution stops.
The following functions have at least one renamed argument:
dissrep(), disstree(), disstree2dot(),
disstree2dotp(), disstreedisplay(), is.eseq(), is.seqelist(), seqdiff(),
seqeconstraint(), seqecontain(), seqecreate(), seqefsub(), seqeid(),
seqelength(), seqelength<-, seqetm(), seqeweight(), seqeweight<-,
seqlegend(), seqpcplot(), seqplot(), seqrep(), seqtab(), seqtrate(),
seqtree(), seqtree2dot(), seqtreedisplay(), seqeisweighted(),
plot.seqalign(), plot.seqdiff(), plot.stslist(), plot.stslist.freq(),
plot.stslist.meant(), plot.stslist.modst(), plot.stslist.rep(),
plot.stslist.statd(), plot.subseqelistchisq().
See the help page of each of
these functions for the mapping between old and new argument names.
Renamed function: is.seqe() was renamed as is.eseq().
Fixed an issue with an example in the documentation page of seqpcplot().
Fixed equation typing errors in seqrep() documentation.
In src/tmrsequence.cpp from TraMineR 1.8-13:
Fixed two memory errors detected by Valgrind.

seqcost(): Evolution of seqsubm() that offers different ways (CONSTANT,
TRATE, INDELS, INDELSLOG, FUTURE, FEATURES) to determine indel and
substitution costs (see the documentation of seqcost() for details). Unlike
seqsubm(), seqcost() returns both the indel and the substitution costs.

New arguments: kweights, tpow, expcost, context, link, h, nu,
transindel, otto, previous, add.column, breaks, step, overlap,
weighted, prox.
sm: value "CONSTANT" has been removed for DHD as it doesn't make sense
and the values "INDELS" and "INDELSLOG" have been added (see seqcost() documentation).
norm: value TRUE is replaced by "auto" and FALSE by "none".
See the updated documentation of seqdist() for details.
seqsubm(): This is now an alias for seqcost(...)$sm.
Registration of native routines for R 3.4.x. See https://stat.ethz.ch/pipermail/r-devel/2017-February/073755.html.
Changes in C-code for the seqefsub function: replaced call
to function round by a call to fround to comply with
forthcoming changes in R 3.4.0 (request of Brian D. Ripley).
The change is transparent for the user.
seqST(): new argument norm to ask for a normalized
turbulence index.
seqformat(): The transformation now stops with an error message
when the columns referenced with the begin and end
argument contain a non integer value.
plot.stslist(): an unnecessary warning occurred when a
vector of labels was passed as ytlab argument.

transformation from SPELL to STS.
fixed bad use of extern "C" {} in TraMineR.h
(done by B. Ripley, CRAN version 1.8-11.1)

seqmeant computes
the variance and standard deviation of the total times spent in the
different states, and the standard error of the mean total times.
seqmtplot(): When serr=TRUE, error bars are displayed in the
mean time plot.
seqdist():
New error message when sm=NA with method "OM".
New error message when refseq is a state sequence object with

Updated help pages: seqeconstraint, seqtree, distree2dot.
Added required basic packages to the import statements to comply with R v3.3 requirements.
One additional exported alias to a TraMineR internal function:
TraMineRInternalSeqgbar.

The filter argument can now simply be a scalar, in which case
the minfreq filter is applied with this numeric value as threshold.
See also the new function seqpcfilter().
New argument missing to control whether and how to display missing
values.
seqformat(): fixed error occurring when converting from STS to TSE
with a tevent matrix containing empty strings (i.e. "")
dissmfacw(): reported F values now obtained by dividing the within
discrepancy in the denominator by (n-m), where n is the sample size
and m the total number of predictors (contrasts for categorical
factors). Up to here (n-m-1) was mistakenly used
(Reported by Vicente Ponsoda.)
Two additional exported aliases to TraMineR internal functions:
TraMineRInternalSeqeage and TraMineRInternalLegend.

by id in inputted TSE data. (Reported by Nicolas Jay).
This requirement is now specified in seqecreate help page.
exported alias functions allowing other packages to access TraMineR
internal functions (see ?TraMineRInternalLayout).
seqpcplot(): Suppressed unnecessary output argument. The
seqpcplot object is automatically retrieved when using the
assignment operator, e.g., p <- seqepcplot(...).
seqformat(): When converting from STS to TSE, an error was raised if the
tevent matrix had empty strings (i.e. ""). Now, this is considered as no event.

would not be found, you can specify the GraphViz installation
directory with the new gvpath argument.
disstree() and seqtree(): removed the warning when R equals 0 or 1 (no permutations).

failures in finding plot positions for sequences. The error
message advices to modify the (currently hidden) maxit argument.
Additionally, automatically generated subtitles are now hidden
when the argument title is used.
as.character.seqelist(), print.seqelist(): fixed an issue with time
display in event sequences which was in scientific notation for numbers
with more than 2 digits. The function now uses the R format function and
thus accounts for global formatting options such as options(digits=)
and/or options(scipen=).
seqtrate(): fixed error with sequence objects having only two columns.
disstree2dot() and disstree2dotp() gain a new argument called title.outer.
If title.outer=TRUE, the title is printed in the outer margins.

seqtreedisplay(): corrected a bug when using representative sequences and
a dist object was passed to the dist.matrix argument (reported by
Emanuela Struffolino).
seqLLCS() and seqLLCP(): added a check on the argument. Both sequences
should belong to state sequence objects with a common alphabet.
seqpcplot(): small change in default lower ylim.
help pages updated with author and keyword fields.
seqrep(), dissrep(), seqrplot(): wrong (unweighted) "na" values were returned;
also quality measures "MD" (mean distance to representative) and "V"

selected (since version 1.8-2).
Added an internal function to fix an issue with an internal C level function when called from other packages.
Updated online help pages.
Updated list of references returned by citation("TraMineR").

parameters and thus corresponds to the colors/shades used in the plot.
seqplot(): if group argument is a factor, the plots are
now ordered the same way as the factor levels.
seqplot(), plot.stslist(): if sortv is a factor, the
sequences are now sorted according to the order of the factor levels.

attribute occurences of object returned by seqmodst to
occurrences. Made resulting changes in plot.stslsit.modst.

Joshi's 5 counting methods (see the ref manual page). The method should be
specified with seqeconstraint().
seqeapplaysub(): when method=NULL is specified (now the default), the count method assigned to the event sequence object is used. With method="count" CDIST_O (number of distinct occurrences) is used as previously.
seqrep(): attribute Index of the returned object is now a vector instead of an object of class dissrep.
seqtreedisplay(): was changing current directory when an error occurred in
the plotting function.

seqdss(), seqdur(): fixed bad handling of missing values in several cases:
sequences finishing with missing values,
sequences made of only one distinct state and missing values.

seqplot() and aliases: fixed error with xaxis argument.
seqtransn(): the returned normalized number of transitions for
sequences of length 1 was NaN (value of transn.norm=0/seqlength-1). Now set to 0.

seqient(): new option base for choosing the base of the logarithm used
to compute the entropy.

seqformat() when converting from "SPELL":
new error message when a start time is lower than 1 and/or an end time is smaller than the start time.
warning message when start time of episode 1 is missing (sequence creation is skipped)
warning message when start/end time of an episode is missing (episode is skipped and filled with NA's)

ex1 example data set: contains now an additional sequence 's7'
with only missing values.
seqdef(): now checks whether all states encountered in the input data are present in an optional user provided alphabet (state argument)
seqefsub(): The support of a subsequence with a total support of 1 was set to 0 (hence, this only applies if the minimum support is 1.) This is now corrected (Reported by Anna Hera).
Corrected compilation problems under SOLARIS (Reported by Prof Brian Ripley).
seqformat(): when converting from SPELL to STS, the fillblank argument was not used.
Added a startup message when loading the TraMineR library.
seqtab() and seqfplot(): tlim argument now allows to return any selected frequent sequences,
in the same way as the tlim argument used in plot.stslist() and seqiplot() (Requested by G. Ritschard).
For example, tlim=3:6 returns the third, fourth, fifth and sixth most frequent sequences in the set. Default for tlim is now 1:10 instead of 10.

on the Y-axis in sequence index plots (if set to "id", the sequence ids are displayed).
An additional ylas option sets the orientation of the labels (Requested by Andrew ??
and P. Jeuniaux).
seqsubm():
When method="TRATE", the substitution costs are now based on the value of cval: SC(i,j) = cval -P(i,j) - P(j,i) where P(i,j) is the transition rate from state i to j.
added a new transition argument to use only transition from "previous" or "next" state
instead of the default "both" when time.varying = TRUE.
Now, by default cval equals 2, unless transition is set to both and

successive states resulted when there were missing values between two identical states.
For example, before: DSS of "A-A-*-A-*-A" was "A-A-A" and now "A".
summary.stslist(): added information in the output of the summary method
for state sequence objects.

new weighted argument. If set as TRUE sequence bar widths are set
proportional to weights.

the sum of weights (if weighted=TRUE and the sequence object has weights)
instead of the number of sequences.
seqfplot() / plot.stslist.freq() and seqdplot() / plot.stslist.statd():
when weights are used, i.e. when the weighted=TRUE argument is passed
and the sequence object has weights,
the ‘n=...’ in the y axis legend now gives the sum of weights instead of the number of sequences;
‘weighted’ is specified in the y axis legend;

seqrep() can now be plotted with their plot() dedicated methods (see
new classes and methods below).

are displayed, while with yaxis="pct" individual sequence percentages
are shown.
pbarw=TRUE is now the default for the pbarw argument.
seqtab(): the format argument that specifies the format of the sequences
displayed as rownames is now set by default to the short SPS format,
e.g. TR/9-EM/63.

seqiplot(), seqmtplot() work as in the previous version but by
calling plot.stslist with the appropriate type= option
(types are 'd', 'f', 'i' and 'mt'). However, the order of the
functions' arguments may have changed and this may cause problems
if the names of the arguments were not explicitly specified in your
scripts (which is inadvisable anyway).

New group option allowing to draw several plots for the levels
of a factor within a single command;
TraMineR now uses layout for controlling the position of the
plots and the legend in the graphic area. This is not compatible

one must set the use.layout=FALSE option in the plot functions;
seqmtplot(): new function that plots the mean time spent in each state;
Option withborder=FALSE is now obsolete and replaced by the standard border=NA option.
New plot for exhibiting discriminant subsequences (seqecmpgroup).

options SPS.in and SPS.out for defining the separator and surrounding
characters used for specifying the state/duration couples.
