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
?? do not give you a satisfactory answer, here are the main information referrals.
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.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.
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
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.
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 to share your resources in comments.
