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

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.
