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
