Hadlye Wickham has done some amazing work in R (ggplot2, plyr and dplyr). Despite R being a bit weird and annoying at times, his packages continue to make it the most compelling option for data analysis (though Julia is catching up!). Thanks, Hadley, for all the hard work.
I thought Julia was still way behind both R and Python when it comes to plotting and stat packages.

#21When I started using Python, it was pretty far behind R. No dataframes, barely any stats, etc. It caught up fast. Julia will do the same.
