Hi All

any one encountered this error before ?


I have the following error when using pvlcust for a transposed matrix.
Please advise how I can get bp/au values when clustering by rows ?
Looking forward to your reply

Thanks a lot
yours,
Alyaa

pv <- pvclust(as.matrix(t(bb)), method.dist="correlation",
method.hclust="complete", nboot=10)
