Getting started with seplyr

A big “thank you!!!” to Microsoft for hosting our new introduction to seplyr. If you are working R and big data I think the seplyr package can be a valuable tool.

For how and why, please check out our new introductory article.

Note: now that wrapr version 1.0.2 is up on CRAN all of the examples can be re-written without quotes using the qae() operator (“quote assignment expression”). For example:

library("seplyr")#> Loading required package: wraprpackageVersion("wrapr")#> [1] '1.0.2'plan <- partition_mutate_se(  qae(name := tolower(name),      height := height + 0.5,      height := floor(height),      mass := mass + 0.5,      mass := floor(mass)))print(plan)#> $group00001#>            name          height            mass #> "tolower(name)"  "height + 0.5"    "mass + 0.5" #> #> $group00002#>          height            mass #> "floor(height)"   "floor(mass)"
