[R] Scree diagram,

[Muhammad Rahiz]

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
