I’ve loved R since the first time I used it in statistics class. I went several years without using it, but I probably should have pulled it out a few times. It’s incredibly powerful and ends up being quite fun for data visualization geeks. Unfortunately, it’s not intuitive to a lot of users.
Further, even those of us comfortable with it seem to quickly forget exactly how we displayed the data just the way we wanted last time. I’m going to post the tricks/scripts I write whenever I use R – both for others and myself to re-use. Just click on the tag R.
