R help - Mar 2019 - arsenal v3.0.0: An Arsenal of 'R' Functions for Large-Scale Statistical Summaries

I'm pleased to announce the release of the "arsenal" package
v3.0.0 on CRAN (https://cran.r-project.org/package=arsenal)!

"arsenal" has experienced some major growth in the last few months,
starting with the release of v2.0.0 in January.  We tried to maintain backwards
compatibility wherever possible, but had to eliminate it in some places.  With
that said, here's the latest and greatest of "arsenal":


1.      The compare() function was renamed to comparedf(), to avoid conflicts
with the "testthat" package.  comparedf() is used to compare two
data.frames, and now includes additional functionality to specify which
variables should be compared if they have different column names.

2.      tableby() is our Table-1-like function.  It now accepts a strata term
and multiple left-hand-side terms.

3.      paired() piggybacks off of tableby() for comparisons across two time
points.

4.      modelsum() runs [lm, coxph, glm, etc.] models on multiple variables,
adjusted for the same covariates.  It also accepts a strata term and multiple
left-hand-side terms.

5.      freqlist() generates frequency tables, much like SAS's "proc
freq" with the "list" option.  It, too, accepts a strata term and
multiple left-hand-side terms.

6.      write2html(), write2pdf(), and write2word() are capable of outputting
tables to documents without needing to open a whole new .Rmd script.

7.      formulize() is a useful function for creating formulas from character
vectors (or columns of data.frames).

As always, contributions and bug reports are welcome on arsenal's GitHub
page: https://github.com/eheinzen/arsenal

Cheers!
