Any of you computer savvy types proficient in R? I learned stat computation using a GUI (GraphPad Prism). Prism is nice, it makes stuff for you as you run tests. But its like paint by numbers compared to a command interface like R. Been trying to pick it up, particularly for its modelling capabilities, but my brain doesn't like computer logic. Could use some pointers, particularly with looping and subsetting. I get the concept, but knowing what little pieces I need to do what in the program is getting me.
