read.table, with the appropriate options. You can see what they are by typing ?read.table at an R prompt. > 2) Which is the best principal component anlysis package in R? Best for what? I'd start with ?princomp and if that doesn't meet your needs go looking farther. www.rseek.org is good for finding R functions for particular purposes. But if you're starting with the correlation matrix rather than the raw data, you might need to do the eigenanalysis yourself rather than relying on an existing function that assumes raw data.
