I'm familiar with dplyr but haven't really used it. I prefer using stuff that's mature, and I'm sure that dplyr is going to undergo a lot of evolution in the early days. I independently came to the same conclusion as this guy: http://blog.datascienceretreat.com/post/69789735503/r-the-good-parts http://blog.datascienceretreat.com/post/69789735503/r-the-go... That is, "use everything from Hadley, except use data.table instead of plyr". This was before dplyr came out, so maybe that could change. But I kind of like the syntax of data.table, although I don't understand all of it. Of course plyr is ridiculously slow and can't be used for even modest-sized data sets.
