I think the new packages from Hadley Wickham are beautiful and straight forward. https://cran.rstudio.com/web/packages/dplyr/vignettes/introduction.html https://cran.rstudio.com/web/packages/dplyr/vignettes/introd... End example from a airplane arrival and departure dataset: flights %>% group_by(year, month, day) %>% select(arr_delay, dep_delay) %>% summarise( arr = mean(arr_delay, na.rm = TRUE), dep = mean(dep_delay, na.rm = TRUE) ) %>% filter(arr > 30 | dep > 30)

Well yeah, and I use them, but they're a bandaid over the fundamental problem that just like in Perl, in R TIMTOWTDI. It's the classic 'we have 12 standards, time to make a unifying one - now we have 13' problem. I've sort of gotten used to it now, but it was majorly difficult at first for me (after having programmed for nearly 20 years) to get used to the concept that any task can be done in 20 different ways, each one just as 'valid' or 'easy' or 'maintainable' as the others. At least in C++ there are 20 bad ways to do something, and one good one - the way that Sutter covered in his columns. I know it's not quite fair to compare 'just' the C++ programming language to R and all its packages, but still.
