Some useful links for GenStat and R
GenStat
GenStat is published by VSNI international, who have a quick start guide and a selection of tutorial videos on their website.
R
This website is written in R: all code used in the notes is available in R markdown (.Rmd) files on GitHub here.
If you’re programming using R, I would recommend the IDE RStudio (download from here) and following chief scientist Hadley Wickham for latest developments in the tidyverse, a collection of packages for data analysis.
