Rhome {base} | R Documentation |
Return the R home directory.
R.home(component="home")
component |
As well as "home" which gives the R home
directory, other known values are "bin" , "doc" ,
"etc" , "modules" and "share" giving the paths to the
corresponding parts of an R installation. |
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.
It can be found outside an R session by R RHOME
.
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.
On Windows the value is guaranteed not to contain spaces, using the
8.3 short form of path elements if required. The value of
R.home()
will typically use backslashes as the path separator,
whereas from R 2.13.0 the value of R_HOME will use slashes
(since too many package maintainers pass it unquoted to shells, for
example in Makefiles).
