names' (rows) and the names of the 'response variables' (columns) are shown
as simple numerals (rather than the column and row names). How might I

< m1 <- mantelkdist(kdist(data gene, data geo),999)
< plot (m1).
The script produced two sub-plots: one showing an xy plot of gene(x) end

I am new at 'R' and not even sure whether I am contacting the appropriate
forum!! However, I have carried out several mantel tests (using 'R') on
genetic data and would like to plot the results in the form of a histogam of
the distribution - and preferably use a procedure that shows the critical
