%description
Tools for transforming 'R' expressions. Provides functions for finding,
extracting, and replacing patterns in 'R' language objects, similarly to
how regular expressions can be used to find, extract, and replace patterns
in text. Also provides functions for generating code using
specially-formatted template files and for translating 'R' expressions
into similar expressions in other programming languages. The package may
be helpful for advanced uses of 'R' expressions, such as developing
domain-specific languages.
