Allowed for zero-dimension edge cases in
cov_to_chol() and chol_to_cov().
Added function map_indices() that maps indices from
an input vector to corresponding sequences of grouped indices.
Added function M() for taking differences such that
the resulting vector is negative.
Removed function renv_development_packages() and
argument use_logo in package_logo() to get rid
of dependency to {usethis} package.
Extended input_check_response() to allow for
multiple alternative checking criteria.
Improved documentation of diff_cov(),
undiff_cov(), and delta().
Improved documentation of dmvnorm() and
rmvnorm(). The mean vector can now be of length 1 for
convenience. The degenerate case (covariance is zero) is now supported.
Also separate dimensions of Sigma can be degenerate for
rmvnorm().
Added function split_vector_at() to split a vector
at specific positions.
Allow for zero matrix in cov_to_chol().
Added function round_data.frame() that rounds
numeric columns of a data.frame.
Added function print_data.frame() that prints a
(possibly abbreviated) data.frame.
Renamed function group_data_frame() ->
group_data.frame().
Renamed function delete_data_frame_columns() ->
delete_columns_data.frame().
Added function quiet() to silence
expressions.
Added functions dtnorm() and dttnorm()
to calculate the density of a (two-sided) truncated normal
distribution.
Added function correlated_regressors() to simulate
correlated regressor values.
Improved documentation.
Removed functions check_date() and
find_closest_year() (too special, only needed for
{fHMM} package).
Added function identical_structure() to check if two
objects have the identical structure.
Fixed bug in matrix_diagonal_indices(): did not
always return integer.
vector_occurrence() to find the
positions of first or last occurrence of unique vector elements.Added function chunk_vector() to split a vector into
chunks.
Added function insert_matrix_column() to add a
column to a matrix.
Added function insert_vector_entry() to add a entry
to a vector.
Renamed basic_package_sticker() ->
package_logo() and added a demo.
Added function matrix_diagonal_indices() that
returns the indices of the diagonal elements of a quadratic
matrix.
Fixed bug in check_numeric_vector():
null.ok did not work.
Added function subsets() that generates subsets of a
vector.
Fixed bug in system_information(): do not fail if
information cannot be retrieved.
Removed HMM code and plot_sequence() function (both
do not really fit in this package).
Added more vignettes to illustrate use cases.
Fixed bug in checks for matrices by checking for NA,
NaN and infinite values.
Increment RoxygenNote to 7.3.0.
Added function system_information() that returns
some general system level information.
Added functions check_list_of_lists(),
test_list_of_lists(), and
assert_list_of_lists().
Added functions check_numeric_vector(),
test_numeric_vector(), and
assert_numeric_vector().
Fixed a bug in merge_lists(), where
NULL elements got erroneously ignored.
function_arguments().Added function check_date() which checks if the
input has the correct date format.
Added function find_closest_year() which finds the
closest year to a given date.
Added function match_numerics() which matches the
indices of two numeric vectors as good as possible (that means with the
smallest possible sum of deviations).
Added function simulate_markov_chain() which
simulates a Markov chain.
Added function
sample_transition_probability_matrix() which samples a
transition probability matrix.
Added functions test_covariance_matrix(),
test_correlation_matrix(),
test_transition_probability_matrix(), and
test_probability_vector() (which are the “test” version of
the corresponding “assert” functions).
Added argument tolerance for covariance matrix,
correlation matrix, transition probability matrix, and probability
vector check functions to account for machine epsilon and avoid false
positives.
Added functions ll_hmm() and
simulate_hmm() to compute log-likelihood and simulate data
from hidden Markov model.
Added argument on_time_out to function
timed() that defines what action to take if the evaluation
time exceeded (error, warning, or silent).
Added support to select identifier = "all" in
Index object and to suppress warnings (if unknown
identifiers were selected) (globally) via the
$hide_warnings field.
Added argument logical to Index object
to combine multiple identifiers either with logical and or logical
or.
Added function unexpected_error() that handles an
unknown error.
Added function group_data_frame() that groups a
data.frame according to the values of a column.
Added function delete_data_frame_columns() that
deletes columns of a data.frame.
Added function renv_development_packages() that
creates a file that loads development packages so that
{renv} can detect and write them to the lockfile.
Added function plot_sequence() that plots a sequence
of numbers.
Renamed Index -> Storage.
Initialized a package website with {pkgdown} and
started to add vignettes.
Added function timed() which evaluates an expression
and interrupts the evaluation after a defined amount of
seconds.
Added function do.call_timed() which measures the
computation time of a do.call() call.
Added function try_silent() which tries to execute
an expression and returns a string with the error message if the
execution failed.
Added R6 object Index that provides a simple
indexing interface for list elements.
Modified basic_package_sticker(): Option to add
brackets to package name, now scales font, the function is no longer
exported.
Added function function_body() which extracts the
body of a function.
Added function permutation() which creates all
permutations of a given vector.
Added function variable_name() which tries to
determine the name of a variable passed to a function.
Added function function_defaults() which returns the
default function arguments.
Added R6 object Dictionary that provides a simple
simple key-value interface.
Added function merge_lists() which merges
lists based on their element names.
Renamed arguments in function timed():
expr -> expression, secs ->
seconds.
Added argument units to function
do.call_timed().
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
