Where can I find useful R tutorials with various implementations?

Question

I'm using R language and the manuals on the R site are really informative. However, I'd like to see some more examples and implementations with R which can help me develop my knowledge faster. Any suggestions?

Answer 1

All the packages on CRAN are open source, so you can download all the source code from there. I recommend starting there by looking at the packages you use regularly to see how they're implemented.

Beyond that, Rosetta Code has many R examples. And you may want to follow R-Bloggers.

Book like tutorials

Book like tutorials are usually spread in the form of PDF. Many of them are available on the R-project homepage here:

http://cran.r-project.org/other-docs.html#english

(This link includes many of the texts others have mentioned)

Article like tutorials

These are usually present inside blogs. The biggest list of R-bloggers I know of exists here:

And many of these bloggers posts (many of which are tutorials) are listed here:

(although inside each blog there are usually more tutorials).
