#12I really like this, but one big complaint is that the auto-scroll after completing a little task isn't correct. So each time after I "pass" a particular section, I have to manually scroll down with my trackpad.
Gregg here from Code School.. we actually tried making it autoscroll down at first. It was too distracting and annoying. Scrolling down when you're ready to continue just felt more natural.

#13This is great. I've nearly completed a class at UC Berkeley which was almost entirely in R and I can say with certainty that it is a marvelous language. It is powerful, concise, and has an incredibly robust community. I've experimented with many programming languages, but I have not used one which allows you to experiment as rapidly as R. I'm currently going through the Codeschool lessons to see if there is anything…

Looks great. Downloading it now. (Thanks for the heads-up!)

Yes! I thought I would never find this again! Thank you so much!

#15For anyone interest in R without a background in statistics: I would highly recommend learning the two in parallel (if not statistics first).
R is first and foremost a language for statistical computing. You really aren't going get much out of it without working on some interesting data/stats problems. Plus for most hacker types I think being able to play with the statistics you're learning about with R can be a great learning aid.
However not only is it beneficial to learn stats with R, it is imho dangerous to learn R without some stats. There's already too much research being published with were 'p-value' means "the thing that t.test() output that I was told needs to be in the paper".
Because R lets you play so freely with stats I find it a great tool to gain greater intuition about certain mathematical principles, but there is a temptation to let the tool do the work and the thinking for you.

#16Just started this now. It's really awesome. Only wish it was a bit faster.

This is a very, very good point. Though, many of the functions that R provides just won't make any sense at all if you don't have an intuition for the statistics behind it. I have found myself reading the papers published about specific functions in order to understand the results.
Do you have any resources that you suggest for beginners in statistics looking to learn on their own?

#18I got a random hang after typing hel( instead of help(
also on sqrt( of a vector.
Also paste works when you shouldn't be able to type.

#19I'm constantly impressed by the high quality content that Gregg and the rest of the Code School folks put out on a regular basis and Try R is no exception. Really excellent work! Looking forward to getting through the rest of it.

#20Thanks. I was sorely disappointed yesterday when I found out that Coursera classes follow a strict schedule (and that I couldn't look at the material right then) and that I wouldn't be able to try the Data Analysis with R course on their site. I'll definitely check this out :).
