bug in princomp example (PR#14167)

Wed, Dec 23, 2009 4:50 PM #

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

try rm(x) before you run the example; I think you might
have an 'x' hanging around in your workspace.
I had no trouble with the example run in a clean workspace.
