Value
Description
Return the R home directory, or the full path to a component of the
R installation.
Usage
1
R.home(component = "home")
Arguments
component
As well as "home" which gives the R home
directory, other known values are "bin", "doc",
"etc", "include", "modules" and "share"
giving the paths to the corresponding parts of an R installation.
Details
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.
Value
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 need not be the case in a Unix-like
installation.
The value for "modules" and on Windows "bin" is a
sub-architecture-specific location.
On a Unix-alike, the constructed paths are based on the current
values of the environment variables R_HOME and where set
R_SHARE_DIR, R_DOC_DIR and R_INCLUDE_DIR (these are
set on startup and should not be altered).
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. The value of R_HOME is set to use
forward slashes (since many package maintainers pass it unquoted to
shells, for example in ‘Makefile’s).
