Hello Gustaf, List. Thanks Gustaf for your post! well I am working pretty intensively with fisher.test() right now, as some of you will know. The comparison is not fair: R's fisher.test() does a whole bunch of error checking and testing for the size of the input matrix and assessing of other a

Hi all, Reading the wikipedia page on R, I stumbled across the following: http://fluff.info/blog/arch/0172.htm It does seem interesting that the C execution is that much slower from R than from a native C program. Could any of the more technically knowledgeable people explain why this is so?
