add_lib | R Documentation |
Prepend/append paths to the library path list, using .libPaths
.
add_lib(..., append = FALSE)
... |
paths to add to .libPath |
append |
logical that indicates that the paths should be appended rather than prepended. |
This function is meant to be more convenient than .libPaths
, which requires
more writing if one wants to:
sequentially add libraries;
append and not prepend new path(s);
keep the standard user library in the search path.
Returns the new set of library paths.
ol <- .libPaths()
# called sequentially, .libPaths only add the last library
show( .libPaths('.') )
show( .libPaths(tempdir()) )
# restore
.libPaths(ol)
# .libPaths does not keep the standard user library
show( .libPaths() )
show( .libPaths('.') )
# restore
.libPaths(ol)
# with add_lib
show( add_lib('.') )
show( add_lib(tempdir()) )
show( add_lib('..', append=TRUE) )
# restore
.libPaths(ol)
