A collection of useful tools for programming and writing-scripts.
Several functions are simple wrappers around base R functions that extend
their functionality while also providing some convenient properties<e2><80><93>regular
expression functions that automatically detect look-ahead and look-behind
statements, a read-line function that suppresses incomplete-final-line
warnings and automatically opens and closes connections, a version of
substrings that starts from the end of strings, etc. Other functions are
useful for working with hexadecimal colors, installing packages, omitting
missing data, and showing in-use connections.
