You need to transpose the loadings: > all.equal(unclass(t$scores), + t$scores %*% t(t$loadings) %*% t$projection) [1] TRUE (A tip: Since 't' is used for transposing, it is usually a Good Thing(TM) to avoid using it as a varable name.) -- Bjørn-Helge Mevik ______________________________________________ [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
