RItools 0.3-3

• Adjusted arguments to xtable.xbal() to match the generic. (#131)

RItools 0.3-2

• Adjusted terminology on balanceplot() plots when using absolute=TRUE. (#129)
• Updated some tidyverse/ggplot2 code to deal with deprecations.
• Using bibentry() in citation to address deprecation.

RItools 0.3-1

• Skipped tests that cause problems with systems using the ATLAS linear algebra library.

RItools 0.3-0

• Exporting broom::glance() and broom::tidy() methods for balance test objects, a work in progress (#90).
• Addressed error relating to setting of pseudo-inversion tolerances (#103). xBalance stops short of correcting the error, to maintain back-compatibility; but it gains a new argument, pseudoinversion_tol, with which it can readily be fixed.
• New balanceTest function extends functionality of xBalance:
  • Support for clustered designs
  • More use of formula interface
  • Multiple comparison adjustments for individual covariate tests
  • Support for unit level weighting
• Introduced ggplot2 based plotting. Optional for xBalance objects; default for new balanceTest objects.

RItools 0.2

This was an internal release not placed on CRAN.

RItools 0.1-18

This is a maintenance release.

• Ensured that the package was compatible with R 4.1.2

RItools 0.1-17

This is a maintenance release.

• Ensured that the package was compatible with R 3.6.0

RItools 0.1-16

This is a maintenance release.

• Fixed a problem where the test suite was calling an external package that was not a formal dependency of the core functionality of the package.

RItools 0.1-15

This is a maintenance release.

• Fixed an obscure bug in which we indirectly fiddled with data.table related global options (#69)
• Disabled tests of RSVGTipsDevice-dependent functionality on Windows platforms, where (as of this writing) RSVGTipsDevice does not build and check reliably and is not distributed in binary through CRAN (#71)

RItools 0.1-14

This version was submitted to CRAN prematurely and ultimately was not released.

RItools 0.1-13

• With xBalance(), you can now specify strata “foo” and “bar” by including “+ strata(foo) + strata(bar)” in the fmla argument, without need to give a separate strata argument (eg strata=list(foo=~foo, bar=~bar)).

RItools 0.1-12

• Switched to base graphics instead of the lattice package for balance plots.
• Option to make plots on absolute, instead of signed, values.
• Added the ability to include tooltips to balance plots when using the RSVGTipsDevice package.
• Added a balanceplot() function to handle plotting matrices, not just xbal objects.
• Balance plots can be grouped into related variables. By default factors are automatically grouped for xbal objects.
• Some performance improvements when certain results are not requested.
• post.alignment.transform argument to xBalance() allows modifying the data after per-stratum centering.
• subset method for xbal objects.

CHANGES in RItools v. 0.1-11

NEW FEATURES

• the null SD of the difference in adjusted means is now reportable as “adj.means.diffs.sd”
• report="all" provides all relevant statistics
• Entering args(xBalance) is now useful as a reminder of report= options.

DEPRECATED & DEFUNCT

• The default imputation method for missing data is the median. Before 0.1-9 it was the mean. To use the mean, use impfn=mean.default.
• Passing strata=NULL to xBalance() is depracated, as it can be easy to do inadvertently, with a misspelling of a non-null intended argument. For no stratification, use list(unstrat=NULL), as is now the default.

BUG FIXES

• display, align, etc arguments to xtable.xbal() have been enabled.
• In xBalance(), when specifying a stratification using a formula with several variables, as in ~x+y, the stratification you get is now interaction(x,y) rather than just y.
