Look at your matrix: x<-matrix(0.5,30,30) x Try the following: x <- rmultinom(30, size = 30, prob=rep(c(0.1,0.2,0.8), 30)) PcaCov(x) Regards, Mark. ----- Mark Difford (Ph.D.) Research Associate Botany Department Nelson Mandela Metropolitan University Port Elizabeth, South Africa -- View this message in context: http://r.789695.n4.nabble.com/Package-rrcov-functions-PcaCov-PcaHubert-PcaGrid-tp3664644p3664961.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
