**There is grandeur in this view of life » R**, and kindly contributed to R-bloggers)I am doing a second installment of the lunch seminars about data analysis with R for the members of the Wright lab. It’s pretty much the same material as before — data frames, linear models and some plots with ggplot2 — but I’ve sprinkled in some more exercises during the seminars. I’ve tried emphasising scripting a bit more than last time, and made a lot of use of RStudio. Going through this first part has taken four hours, but that includes each seminar a quick review of what we did last time and lots of questions. Next week we’ll get started on gene expression microarray data, and I’ll try introducing both *limma* and *plyr*.

(My previous introduction materials are posted here.)
