A lecture on using PCA in Computational Biology
In order to build the document you need to first run both SetUpGO.R and OSCAmultisample.R.
The latter takes quite a while to run, and you might instead just edit out those slides from the lecture.
There is a file, package_versions.csv that contains a list of all the packages you need.
They are obtained by running sessionInfo() after having sourced both of the other scripts.
