search for: explvar

Dear R-help users, I'd like to use the R-package "pls" and want to extract the explained Y-variance to identify the important (PLS-) principal components in my model, related to the y-data. For explained X-variance there is a function: "explvar()". If I understand it right, the summary() function gives an overview, where the y-variance is shown, but I can't extract it for plotting. How can I do it, withou pencil and paper? Thank you very much for help, Christian
