Hellow, I am running a set of simulations with distance matrices used as input to pcoa (package ape).
In one instance the matrix (DH) is H18 H20 H21 H18 0.0000000 0.3127452190 0.3127452190 H20 0.3127452 0.0000000000 0.0001625185 H21 0.3127452 0.0001625185 0.0000000000 when I run pcoa I get this H.PCo <- pcoa(DH, correction="none")$vectors Error in array(STATS, dims[perm]) : 'dims' cannot be of length 0 However, if I multiply DH*10 pcoa runs just fine: H.PCo <- pcoa(DH*10, correction="none")$vectors A word of explanation will be very much appreciated.
