"An Introduction to R" is the basic introduction. You should read that first, then go to the help pages when you need detailed technical information about a particular function. To see the manuals, run help.start() and click on one of the links near the top of the page. If your problems are with help pages from contributed packages, then you should look for vignettes in the package. Not all packages have them, but it's a sign of a lack of interest in documentation if they don't: and I'd recommend avoiding such packages. To see the vignettes for "somepackage", run browseVignettes(package = "somepackage") Duncan Murdoch

Recently I found it really useful to list the functions of a recently installed package somepackage, using these to lines: library(somepackage) ls.str('package:somepackage') I just put them in a script to run it quickly in the shell like this: #!/usr/bin/env Rscript pkg <- commandArgs(trailingOnly=TRUE)[1] text <- paste0("library(", pkg, "); ls.str('package:", pkg, "')") eval(parse(text=text)) Best, Rasmus -------------- next part -------------- A non-text attachment was scrubbed...

Dear Pedro If you prefer reading in Spanish which from your name may be the case then if you go to CRAN, click on Documentation | Contributed you will find some documentation in Spanish including several aimed at beginners. There are some in Portuguese as well if I have mis-interpreted your name. Of course ultimately you may prefer to read the documents in English because the program help and vignettes are usually in English and familiarity with the English terminology may help.

Hi Pedro, Reading R help pages definitely takes practice. Here's a tip: when you bring up the help page, scroll down to the bottom to see if there are examples (there usually are.) I find that seeing examples often provides enough information to let you figure out what you need to do.
