reduce_plan: Write commands to reduce several targets down to one....

In drake: A Pipeline Toolkit for Reproducible Computation at Scale

Write commands to reduce several targets down to one.

Description

Deprecated on 2019-05-16. Use drake_plan() transformations instead. See ⁠https://books.ropensci.org/drake/plans.html#large-plans⁠ for the details.

Usage

reduce_plan(
  plan = NULL,
  target = "target",
  begin = "",
  op = " + ",
  end = "",
  pairwise = TRUE,
  append = FALSE,
  sep = "_"
)

Arguments

plan	Workflow plan data frame of prespecified targets.
target	Name of the new reduced target.
begin	Character, code to place at the beginning of each step in the reduction.
op	Binary operator to apply in the reduction
end	Character, code to place at the end of each step in the reduction.
pairwise	Logical, whether to create multiple new targets, one for each pair/step in the reduction (TRUE), or to do the reduction all in one command.
append	Logical. If TRUE, the output will include the original rows in the plan argument. If FALSE, the output will only include the new targets and commands.
sep	Character scalar, delimiter for creating new target names.

Details

Creates a new workflow plan data frame with the commands to do a reduction (i.e. to repeatedly apply a binary operator to pairs of targets to produce one target).

Value

A workflow plan data frame that aggregates multiple prespecified targets into one additional target downstream.
