Last week I held a two-day workshop giving an introduction to GIS with QGIS on the first day, and a basic intro to R (focusing on base R) and spatial analysis with R on the second day. For the workshop I developed some stand-alone tutorials which I've now repurposed and posted online for anyone to use or adjust for their own purposes.
