Try this:

> summary.princomp

Error: object "summary.princomp" not found
> summary.data.frame

function (object, maxsum = 7, digits = max(3, getOption("digits") -

3), ...)

{

R can find summary.princomp when it runs UseMethod, but it's hidden in the stats namespace, so you need to use "stats:::summary.princomp" to see it.
