Dear mailing list members,

 

I got a question about principal component analysis. I know that's not the
main topic here, but perhaps somebody have used it already. I'm wondering
how to get the names of the particular components.

 

Let me give you an example:

 

x <- rnorm(300)

y <- runif(300)

z <- rnorm(300, mean=10, sd=5)

dat <- data.frame(x,y,z)

pca <- princomp(dat, corr=T)

summary(pca)

 

and now I would like to know which is for example the first component?

Can anybody help me?

 

regards
