[R] Stacking Vectors/Dataframes

[Marc Schwartz]

Archived versions of gregmisc (and other packages) are available from:

http://cran.r-project.org/src/contrib/Archive/

Download one of the older versions (ie. 0.8.5) and install it from a
console using R CMD INSTALL.

If you are restricted from installing packages to the main R tree (ie.
you do not have the requisite permissions), see R FAQ 5.2 regarding
installing packages to alternate locations.

HTH,

Marc Schwartz
