[R-sig-eco] Error Between class analysis using bca() on BIOCLIM variables

[Julian WITTISCHE]

Dear all,
I have tried to use the function bca() on PCA results (dudi.pca) :
pca.ade4<-dudi.pca(batrapair[,2:20], center=T, scale=T, scannf=T); 2;
betweenclass<-bca(pca.ade4,fac, scannf = TRUE);2;
and I get this error:
Error in if (nf <= 0) nf <- 2 : 
  missing value where TRUE / FALSE is required

 If you have any idea to solve this please let me know. I attached my script and here is what batrapair looks like
