CHANGES IN RITOOLS VERSION 0.1-17

This is a maintenance release.

• Ensured that the package was compatible with R 3.6.0

CHANGES IN RITOOLS VERSION 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.

CHANGES IN RITOOLS VERSION 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)

CHANGES IN RITOOLS VERSION 0.1-14

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

CHANGES IN RITOOLS VERSION 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)).

CHANGES IN RITOOLS VERSION 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.
