Attached is a folder with some R lessons, starting from loading R, and understanding objects, loading data, etc. It uses some ForestGEO data to do basic things, correlations, ANOVA, regression, basic plots, etc. The third week asks the students to use the data to answer some questions – those could be the things that the students must do before the workshop, perhaps as homework.
I don’t use R Studio (I know, heretical!), so these tutorials don’t involve that.
