forward selection of significant eigenvectors
Dear Irene, i found this tutorial very useful: https://sites.ualberta.ca/~ahamann/teaching/renr690/Lab9.pdf You basically do a forward selection (forward.sel() from packfor package) using the adjusted R-square (RsquareAdj() from vegan package). Hope this helps, Tim Am 06.06.2019 um 16:34 schrieb Irene Adamo:
Dear all, I am trying to run a variaion partitioning in using the varpart function in vegan. I would like to include the geographic coordinates as explanatory variables so I calculated the principle coordinates of neighbour matrices. Now I would like to perform a selection of the significant spatial eigenvectors but I don`t know how to do it in R. Could anybody help me? data(mite.xy) pcnm1 <- pcnm(dist(mite.xy)) then I get the pcnm vectors and I would like to select only the significant ones. Thanks a lot! [[alternative HTML version deleted]]
