  It's almost impossible to answer this question without a reproducible
example.  Does the same thing happen with

fisher.alpha(head(data[[1]])) 

?

If so, can you post the results of dput(head(data[[1]])) 

?

If not, please spend some time cutting the problem down to 
something that can be posted.  If that's really hard, post
your data on the web somewhere and post a link to it.
(Sending attachments to the mailing list is a bit dicey.)
