1) I believe you wanted a scree plot which shows the percentage of
variance explained (y-axis) versus the principal components (x-axis). To
do that, all you needs a simple plot(x,y) function where x = pc and y =
variance. It is called a scree plot because the plot looks like a scree
on the side of the mountain.
2) you can find the details of the components using names(x) where x=
the output from your pca command

hello,
I've two questions today.
1) I'm trying to do a scree diagram, I did a Google for a specific command I
could used to do so. All I could find is a screeplot. Are they the same
command?
2) what command can I used to present a PC scores, eigenvectors of the PC
scores, and component correlations?
thanks!
