databases: as well as in memory data frames, dplyr also connects to databases. It allows you to work with remote, out-of-memory data, using exactly the same tools, because dplyr will translate your R code into the appropriate SQL. benchmark-baseball: see how dplyr compares to other tools for data manipulation on a realistic use case. library(data.table) library(plyr) library(dplyr) library(purrr) library(magrittr) Curve fitting on batches in the tidyverse: R, dplyr, and broom Sep 9, 2018 · 7 minute read · Comments. I recently needed to fit curves on several sets of similar data, measured from different sensors. I found how to achieve this with dplyr, without needing to define outside functions or use for-loops. He then demonstrates more advanced techniques for accomplishing the same task such as data.table, dplyr, Rcpp and parallel computation for increased speed. Finally, for when data size is an even bigger factor than speed he introduces external memory and database techniques using bibmemory, ff, SciDB, dplyr and Hadoop.

Am I misunderstanding something about dplyr's syntax? Is this type of internal subsetting no longer valid, or is there another way to do it? It's a succinct shortcut that's saved me a lot of time and kept my code very readable, so despite dplyr's obvious speed improvements, I can't really switch until I figure out an equivalent. В блоге проекта RStudio, проф. Хэдли Укхэм сообщил о выходе нового пакета для R - dplyr.Те, кто знаком с работой Хэдли, увидят сходство в названии этого нового пакета с plyr - одного из наиболее популярных в настоящее время R ...

Rに標準で入っているtapply関数などでもグループ別の集計ができるが,扱い方が難しく,出力結果も非常に見にくい.それに対し,このddply関数はプログラムが直感的でかつ出力結果もtapplyと比べると見やすくて非常に便利. The first is to make use of the map() suite of functions found in the purrr package, and now implemented in dplyr. This is a very fast tidyverse friendly approach to splitting up tasks. The other good option is to go back in time a bit and use the ddply() function from the plyr package. This is arguably a better approach as it allows us to very ...
