cpan search for fisher came up with the Text::NSP module that contains a leftFisher and a rightFisher test .. do these fit your needs?	[reply]

If you already have working code in R, why not use Statistics::R? (CPAN search isn't picking up the link correctly, but you can use kobesearch to find it.	[reply]

Thanks, I have gone with this as I have the generated code for R. However it is not without problems. My code runs a number of Fisher's tests based on the data in another file. However there appears to be some memory problems. The script freezes at an arbitary point in the loop through the tests. Sometimes it makes it all the way through, sometimes it stops after only the sixth one. Do you know what could be up, whether there's a way of making the bridge more memory-efficient?	[reply]

I've now posted about this in more detail in a new SoPW thread: Perl/R Problem	[reply]

I posted some code for this some weeks ago. Very alpha; you'll probably need to adapt it to your needs. See here. the lowliest monk	[reply]
