### Calculating and adding error bars

Whenever I find myself trying to calculate standard error (or other things) and add error bars to something with multiple factors or groups at play, I find myself eventually googling to this stellar page, which has a handy function at the bottom called summarySE(). (I do note that this is a bit outdated and relies on plyr as written, which may cause problems if you’re using dplyr. So if you hit any snags, maybe check that out first.)

Ok, so that’s all I have in mind at the moment, but now that this page is here, I’ll add more as I use them 🙂
