Dear R users, I am having trouble using the pca function in the multiv library. I am trying to generate the values found in $rproj by using $evecs to calculate linear combinations of my input data. However, I have been not been able to correctly calculate the $rproj values.
Using the following standard sample data, why does iris%*%pcprim$evecs[,] not equal pcprim$rproj? data(iris) iris<-as.matrix(iris[,1:4]) pcprim<-pca(iris) Many thanks, Scott ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
