One general purpose web framework away
It has some really great statistical and data science packages that were well ahead of the competition 10-15 years ago. The web frameworks were good enough for dashboards and what most people were using R for.
But if you wanted to write fast and elegant nom-vectorized code, R is really lacking. I left it for Julia for that reason.
I'm not a fan of pandas, so I'd say Julia and R beat python at basic dataframe manipulation. Nothing beats kdb+/q at dataframes though imo.
