map_plan: Create a plan that maps a function to a grid of arguments....

In wlandau-lilly/drake: A Pipeline Toolkit for Reproducible Computation at Scale

Create a plan that maps a function to a grid of arguments.

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

map_plan(args, fun, id = "id", character_only = FALSE, trace = FALSE)

Arguments

args	A data frame (or better yet, a tibble) of function arguments to fun. Here, the column names should be the names of the arguments of fun, and each row of args corresponds to a call to fun.
fun	Name of a function to apply the arguments row-by-row. Supply a symbol if character_only is FALSE and a character scalar otherwise.
id	Name of an optional column in args giving the names of the targets. If not supplied, target names will be generated automatically. id should be a symbol if character_only is FALSE and a character scalar otherwise.
character_only	Logical, whether to interpret the fun and id arguments as character scalars or symbols.
trace	Logical, whether to append the columns of args to the output workflow plan data frame. The added columns help "trace back" the original settings that went into building each target. Similar to the trace argument of drake_plan().

Details

map_plan() is like base::Map(): it takes a function name and a grid of arguments, and writes out all the commands calls to apply the function to each row of arguments.

Value

A workflow plan data frame.
