Hi all,
I am doing mantel test to look for the correlation between two matrices; genetic matrix and climatic distance matrix using mantel function in vegan r package This my command worked very nice
mantel(x.dist, euc.dist.clim, permutations = 999 , method= "pearson")
But, it's only showing the Upper quantiles of permutations, I am interested to look for the Lower quantiles of permutations as well, is there is a way to do that? the documentation doesn't show such a thing. it would be really great to have the lower quantiles of permutations 10% 5% 2.5% 1% I know that I can use other packages like the ecodist r package, where it shows the lower limit 2.5% and the upper 97.5% but I want to use vegan to show the 4 upper and lower values quantiles of permutations
here is an example of the output results;
Mantel statistic based on Pearson's product-moment correlation
Call:
mantel(xdis = euc.dist.geo, ydis = euc.dist.clim, method = "pearson", permutations = 999, strata = NULL)
Mantel statistic r: 0.3255
Significance: 0.001
Upper quantiles of permutations (null model):
90% 95% 97.5% 99%
0.0390 0.0521 0.0621 0.0732
Permutation: free
Number of permutations: 999
Thanks, Hanin
