Hi all,

I have a difficulty to calculate the PCA scores. The PCA scores I calculated
doesn't match with the scores generated by R,

mypca<-princomp(mymatrix, cor=T)

myscore<-as.matrix(mymatrix)%*%as.matrix(mypca$loadings)

Does anybody know how the mypca$scores were calculated? Is my formula not
correct?

Thanks a lot!

Phoebe
