Is there a way to get biplot and identify to work togheter.

Having the output of prcomp I would like to draw a biplot that. Instead of plotting the sample (row-names) names plots some "pch" symbols. (thats easy with xlabs)

But now I would like to add using identify the names to only some of the points. I have noticed that both biplot.prcomp and biplot.default does a lot of scaling.

So has anyone a function like identify.prcomp please?

Is it possible?
