Hi, If you know the package versions that you wish to cite and they are no longer installed locally, you can use the content of either the CITATION file for the package, if included, or the content of the DESCRIPTION file, for the relevant version of the package. The easiest way to do this may be to download the source tarball for the package from the CRAN archive for the package or wherever the package is located, if not on CRAN. An alternative, if the package is stored in an online VC system (e.g. Github), is that you may be able to read the relevant file from that system for the version of the file that is tagged appropriately.
