I found this one through a link from another R blog. The subject of the particular Post i landed on involved you and Google's chief economist...after a few paragraphs i thought that perhaps this was a celebrity gossip blog or something of that sort. So i glanced at your tag cloud: "Agriculture," "Beer," "Rockstars," among others. Well, i've put it in my RSS feed anyway.

I remember battling with the apply functions when I was first learning R. Although I've grown fairly comfortable with the apply functions, plyr looks slick enough that I may convert (if only to avoid being called quaint...)

The hardest part of apply() is that all the different incarnations seem to have different syntax and different idiosyncrasies. What a pain. With plyr there's a unified abstraction, and thus, less syntax to have to remember. So you watching the Army/Navy game today? -JD Jason, Glad that you got some value from the post!

It's good to know that I'm not the only one with apply-blindness. I don't know how many times I've banged my head against the apply functions, only to give up and do it with a loop, "just this once." My new goal is to grok plyr and then be able to say, "Oh, you're still using apply? How quaint." Great screencast. It’s good to know that I’m not the only one with apply-blindness.

This is exactly why I blog. Also, as was pointed out to me on Twitter: I don't need the c() when I do the yearList and sapply(yearList, getValues) is the same as sapply(yearList, function(x) getValues(x)) Great point Greg!
