In this article, you will find a list of Internet resources that may be useful if you are programming in R. If you have a problem with R and ? or ?? do not give you a satisfactory answer, here are the main information referrals.

RSeek.org

RSeek is a custom search engine that can help you find information on the official website, the CRAN, the archives of the mailing lists, the documentation of R and even selected websites. It is more effective than a simple Google search.

R-bloggers

R-Bloggers.com is a blog aggregator of content collected from bloggers who write about R. It has an effective search tool that allows searching in all articles published by the contributing bloggers.

#R

On the freenode IRC network, the #R channel is quite active (about one hundred members connected when I wrote this article). Feel free to ask questions. Often properly formulating a question helps you finding the answer. You can use the freenode Web IRC client: webchat.freenode.net

Server: irc.freenode.net
Channel: #R

R-help

If you do not find a solution to your problem with the above resources, you can post your question to the R-help mailing list.

Packages

If you encounter a problem with a particular package, contacting the author may be a solution. You can get the address of the package with the command:

packageDescription(pkg = "lattice", fields = "URL")

And the e-mail of the author with:

packageDescription("lattice", fields = c("Author", "Maintainer"))

Feel free…

Feel free to share your resources in comments.
