\alias{add_lib}
\title{Adding Package Libraries}
\usage{
add_lib(..., append = FALSE)
}
\arguments{
\item{...}{paths to add to .libPath}
\item{append}{logical that indicates that the paths should be appended
rather than prepended.}
}
\value{
Returns the new set of library paths.
}
\description{
Prepend/append paths to the library path list, using \code{\link{.libPaths}}.
}
\details{
This function is meant to be more convenient than \code{.libPaths}, which requires
more writing if one wants to:
\itemize{
\item sequentially add libraries;
\item append and not prepend new path(s);
\item keep the standard user library in the search path.
}
}
\examples{
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)
}
