You probably got some missing or undefined values.
Either eyeball the data or use sum(is.na(x)), sum(is.nan(x)),
sum(is.infinite(x)) to find out if you have such data. You may want to
use which() to find out where they are.

I am attempting to run principal components analysis on a dataset of
spectral reflectance (6 decimal places). I imported the data using
read.table and there are both column and row headers. When I run
princomp I receive the following error:
Error in cov.wt(z) : 'x' must contain finite values only
Where am I going wrong?
