Anyone have a SQL code for cumulative F distribution function?

I know it's probably a long shot, but has anyone coded statistical distributions as functions in PostgreSQL? Specifically, I'm looking for a function to calculate the cumulative F distribution. By the way, I know that I can do /df at the psql command line to list the available functions. Is there a help function or better description for a given function? Specifically, I'd like to know what array_in and array_out do. Thanks -Tony

Its available on Sourceforge and from the R Archive: http://cran.r-project.org/ Joe
