The eigenvalues are the squares of the singular values (although you need
to watch the scalings used, in particular n vs n-1). (This is standard
theory.)
Since both are non-negative, given one you can get the other.

Hello,
Can you get eigenvalues in addition to eigevectors using prcomp? If so how?
I am unable to use princomp due to small sample sizes.
Thank you in advance for your help!

I donn't think you can get it directly from prcomp ,but you can get it though
svd.In fact,the prcomp use the svd to do the principal components analysis .

Hi, Rebecca,
From ?prcomp:
The calculation is done by a singular
