That's my root partition you're hogging!

I recently noticed that my / (root) partition was not so slowly running out of space. This was somewhat alarming as I’d given it a generous 23Gb of SSD space which is surely overkill for a Debian install… Well it turns out that the culprit was R, more specifically the default site-library located in /usr/local/lib/R/site-library: $ sudo du -h /usr/local/lib/R/site-library 6.0G /usr/local/lib/R/site-library/ That’s 6Gb of R packages dominating my root directory, thanks Bioconductor!
