.libPaths gets/sets the library trees within which packages are
looked for.

.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 aapplying FUN to the
corresponding element of X.
sapply is a “user-friendly” version of lapply
by default returning a vector or matrix if appropriate.
replicate is a wrapper for the common use of sapply for
repeated evaluation of an expression (which will usually involve
random number generation).
