R help - Feb 2013 - Clean up biplot resulting from princomp()

Dear R-helpers,

The vectors in my biplot are completely obscured by the ~1400 labels R is
printing on my biplot. I don't really care about the labels. How can I make
the biplot without the annoying labels?

See attached, if that helps you see my problem.

Many thanks,

Mark Na

?biplot

set.seed(42)
pcout <- princomp(matrix(rnorm(1000), 100, 10))
biplot(pcout)
biplot(pcout, xlabs=rep(".", dim(pcout$scores)[1])) # small symbol
biplot(pcout, xlabs=rep("", dim(pcout$scores)[1])) # no symbol
