Hi all, I have a distance matrix, created in R (using vegdist). When I use write.matrix to write it to a file, it writes a matrix with values in the upper diagonal. Is it possible to get R to write only the lower diagonal values (since the matrix that it creates with vegdist actually only has lower triangle values)? The help file does not indicate any extra parameters that may aid me. Thanks in advance, Muri ____________________________________________________________________________________ the tools to get online. [[alternative HTML version deleted]]
