The R home directory is the top-level directory of the R installation being run.
The R home directory is often referred to as R_HOME, and is the value of an environment variable of that name in an R session.
A character string giving the R home directory or path to a particular component. Normally the components are all subdirectories of the R home directory, but this may not be the case in a Unix-like installation.
The return value for "modules" and on Windows "bin" is
to a sub-architecture-specific location.
The function R.home() bases the constructed paths on the
current value of the environment variable R_HOME which is
normally set on startup.
On Windows the values of R.home() and R_HOME are
guaranteed not to contain spaces, switching to the 8.3 short form of
path elements if required. From R 2.13.0 the value of R_HOME
is set on startup to use forward slashes (since many package
maintainers pass it unquoted to shells, for example in Makefiles).
