libPaths {base} | R Documentation |
.libPaths
gets/sets the library trees within which packages are
looked for.
.libPaths(new) .Library
new |
a character vector with the locations of R library trees. |
.Library
is a character string giving the location of the
default library, the ‘library’ subdirectory of R_HOME
.
.libPaths
is used for getting or setting the library trees that
R knows about (and hence uses when looking for packages). If called
with argument new
, the library search path is set to
the existing files in unique(c(new, .Library))
and this is
returned. If given no argument, a character vector with the currently
known library trees is returned.
The library search path is initialized at startup from the environment
variable R_LIBS
(which should be a colon-separated list of
directories at which R library trees are rooted) by calling
.libPaths
with the directories specified in R_LIBS
.
A character vector of file paths.
