Data transformation for blockr.core

Extending blockr.core with blocks for data wrangling, blockr.dplyr wraps several dplyr verbs.

Installation

You can install the development version of blockr.dplyr from GitHub with:

# install.packages("devtools")
devtools::install_github("cynkra/blockr.dplyr")

Example

A dplyr::select() block can be spun up as

library(blockr.dplyr)
blockr.core::serve(new_select_block(c("mpg", "cyl")), list(data = mtcars))

A dplyr::mutate() block can be used to add new variables:

library(blockr.dplyr)
blockr.core::serve(new_mutate_block(), list(data = mtcars))

And a two-table verb such as dplyr::join() is available as

library(blockr.dplyr)
blockr.core::serve(
  new_join_block(by = "name"),
  data = list(x = dplyr::band_members, y = dplyr::band_instruments)
)
