Hello R user! I have again a problem and sometimes I have the feeling that I will never learn to solve my problems by myself. But I found no solution in the searchable archieves or somewhere else.
I have a square data.frame with distance values. In this special case the upper and the lower triangle are not the same and the diagonal is not containing zero. I need first the lower triangle including the diagonal (but not as zero) to perform a Manteltest in comparison with another triangle. I tried first as.dist and it worked very well for the lower triangle but then I became aware of the diagonal handling as zero. I found no option to get only the upper triangle including the diagonal in as.dist. Secondly i need also the upper triangle including the diagonal to perform a Manteltest. Could anybody help me with this problem. I appologise in advance, because I was to stupid to find the solution by myself. Thanks a lot.
