Last year I spoke with Marco Trizzino for @ReviewCommons

Trizzino came from a wet lab background before adopting computational approaches. This was his training tip for students & postdocs who want to learn bioinformatics:

"R is really important. Whichever field you work in, it doesn’t matter if you are a neuroscientist or a cancer biologist. There are a lot of resources to learn R, Coursera courses, workshops, and all the universities now have an R class. I would really recommend to everyone to learn R."
