Over the past few years I have taught a one-day workshop on the use of the R statistical software for the analysis of biodiversity data.
Typically I spend a half day giving a general introduction to R and a half day working through some examples of how to use R to analyze ecological and evolutionary data sets.
The files used for the workshop, including data sets and R code, are publicly available and have moved to a new location:
