Hi,
As a biologist who started to learn R, I encountered a lot of problems on learning the subject. Now I don't want to go into them but I just want to suggest what I think that can save you from wasting your time and energy fooling around without getting what you expect.
If I go back to my pre-R era I would follow the above. I think its a good kick-off for those who want to learn R and start getting familiar with R's environment. I hope it helps you =)
Cheers!
R is a bit of a memory hog. Naive approaches can waste a lot of valuable time reallocating memory to data containers. I learned some approaches that try to minimize this pain in Patrick Burns' The R Inferno. Tasks that would take an hour were reduced down to five minute runs. Reading the first few chapters of this PDF will pay dividends, if your time is valuable to you.
Bonus points: you're likely to get a decent chuckle from his writing on a few occasions ...
I also like the course named One Page R: Hands-On Data Science with R

There are a lot of blank pages in those PDFs. Do you know the reason?!
Check with the author - must be some sort of formatting problem where the font was missing

I just stumbled upon this resource today: http://rstatistics.net/
I avoid R as much as possible (I'm not proud of it) largely owing to the unintuitive syntax, but I have a feeling it's a skillset that'll help me someday.
Russian-speaking R beginners should definitely take R courses on stepik.org, they are good and some tasks are difficult and that's good for your brain
I think that R manuals would be most useful. They are very much concise. I don't know, why it is not mentioned in any of the comments above. I find these very useful :-)

Log in to answer this question.
swirlstats looks like a great resource - I have not heard of it before
It is indeed. I guess it is introduced recently by Johns Hopkins department of biostatistics.
Please share what you think can be useful also. I just wanted to provide a beginner/non-IT friendly workflow for people like me who can easily become lost in the labyrinths of tutorials and manuals.
I would add, as someone who started using R around 13 years ago: RStudio has been a complete game-changer. It has made the software far more accessible to more people, brought together a great combination of developers, been responsible for many useful, innovative packages and all-in-all, is just A Good Thing.
It was a game-changer to me also. ِDeciding shall I learn R or not, it was the R-studio that made it possible for me. =)
Dear Parham, thank you so much!! =)
You're welcome! I hope it helped!
Another valuable source is MarinStatsLectures on youtube by Mike Marin. I took a start from here. Check this one too!
I noticed www.codeschool.com is also useful and easy to get although I didn't try myself yet
