The doBy package for is (yet another) R package with utility
functions.
The package originally grew out of a need to calculate groupwise
summary statistics, which explains the origin of the name: "do something on data
which is grouped By some variables".
However, the package now contains many other utilities.

Markup of R-script:
Around 2010 the Rmarkup() function was introduced as a tool for
turning an R script file into an HTML document. The Rmarkup() function has been removed from doBy because it is now obsolete. A
better alternative is to use the markdown and knitr packages. An
example is provided in the script file
Puromycin-markdown.txt. The
HTML document created from the script is
here. The program
wkhtmltopdf does a good job in turning HTML into pdf; the
result can be seen here.
