Funny you mention R. I started a several months work on data analysis/science/you-name-it in python (a good language) and slowly, without noticing it, I migrated all my stuff to R (made by Satan). And exactly for the reason you give: R gets the sh*t done faster (in terms of time spent writing code) than Python... (and you can consider I am a lisper (worse: a schemer)/rust-er at heart !!!)
