Hi During using the R(vision 2.0.1), I meet a problem. I would like to do the Multiple Correspondence Analysis, but when I use the "< mca(lf, nf = 2, abbrev = FALSE)", the sentence "Error: couldn't find function 'mca'" will appear. So, please tell me how can I use the "mca()", thanks! Any help appreciated.... jeff

By requesting 'help.search("mca")', I learned that mca was in "library(MASS)". Did you try "library(MASS)" before your mca command? hope this helps. spencer graves p.s. Using 'help.search' was suggested by the posting guide, "www.R-project.org/posting-guide.html". ys03165003 at student.ecnu.edu.cn wrote:>Hi > >During using the R(vision 2.0.1), I meet a problem.
