The Packages/ directory has some package source tar.gz files. See index.html for a description of the package and the installation procedures. This R package is not in the R package format in the github repository. It was initially developed in 1999 and was intended for use in both S-Plus and R and so requires a different structure for each. make ADMIN=1 copies the files to an appropriate structure for R. It currently requires some supporting tools from the Omegahat admin facilities.
