I am trying to run PCA on a matrix (the first column and row are headers). There are several cells with NA's. When I run PCA with the following code:



setwd("I:/PCA")
AsianProp<-read.csv("Matrix.csv", sep=",", header=T, row.names=1) attach(AsianProp)
AsianProp
AsianProp.pca<-princomp(AsianProp, na.omit)

I get the error message:

cov.wt(z) : 'x' must contain finite values only

What am I doing wrong?

Thanks very much!
