As a quick follow-up to my previous post, I’ll quickly note some R links specifically aimed at psychologists. Jonathan Baron and Yuelin Li have a excellent set of notes that cover ground from R basics to ANOVA (including repeated measures ANOVA) and beyond. Jonathan Baron also maintains a general set of R links. William Revelle’s R guide for psychological research is also very good and has more emphasis on psychometrics than Baron and Li.
Pilgrim’s blog is an R resource for the exercises in the classic Applied Multiple Regression/Correlation Analysis for the Behavioral Sciences text.
