It's amazing to think that R (or S) had data frames since the 70s and only now are other languages implementing them. There are some quirks of course, and pandas introduced some convenient features. But the R community has also provided its own improvements in the way of data.table, and now, dplyr.
- ajinkyakale 12y agoData.table package by matt dowle definitely deserves a mention! Its fast and I like the indexing functonalities it provides. The benchmark timings are pretty impressive.
- arun_sriniv 12y ago@ajinkyakale, thanks. What'd be also interesting is to benchmark memory usage in addition to runtime.
- ajinkyakale 12y agoI should have mentioned you (arun_sriniv) as the co-developer of data.table! Thanks for all the hard work. And yes, memory usage will be interesting as that is the bottleneck when it comes to large dataset. I am working on something on those lines. Will post something soon :)
- arun_sriniv 12y agoNo worries :-). And glad to hear you're working on it! Let me know if I can be of any help.
