What to do when a package is not available for our R version? [duplicate]

Answer 1

Try something like:

packageurl <- "http://cran.r-project.org/src/contrib/Archive/XXXX/XXXX_A.B.C.tar.gz"
install.packages(packageurl, contriburl=NULL, type="source")

where XXXX is your package name and A.B.C is the version of the package (not R).
