Function Reference
has a variety of functions that operate on scalars, matricies,
strings and lists. There are two types of functions —built-in and user-defined. Because some user-defined functions are
very useful, they are loaded automatically when you start . These
are referred to as standard R-files, and are just files containing useful
code that are stored in a special library directory. In
addition, there are other useful functions supplied with the distribution, and you can also define other functions.
Both built-in functions and standard R-files are documented in this
section.
