This package provides a function tidy_source() to format R source
code. Spaces and indent will be added to the code automatically, and
comments will be preserved under certain conditions, so that R code
will be more human-readable and tidy. There is also a Shiny app as a
user interface in this package (see tidy_app()).
Note: this commit is part of reorganizing some of the recently
imported R packages, which are being reimported into more appropriate
categories (and removed from math) as a result of a recent discussion
on tech-pkg and privately with wiz@. See the thread starting with:
