[Rd] bug in princomp example (PR#14167)

[twoutopias at gmail.com]

When I run

example(princomp)

I get the following error message:

prncmp> ## The variances of the variables in the
prncmp> ## USArrests data vary by orders of magnitude, so scaling is
appropriate
prncmp> (pc.cr <- princomp(USArrests))  # inappropriate
Error in cov.wt(z) : 'x' must contain finite values only
