id_chr {drake}R Documentation

Name of the current target [Stable]

Description

id_chr() gives you the name of the current target while make() is running. For static branching in drake_plan(), use the .id_chr symbol instead. See the examples for details.

Usage

id_chr()

Value

The name of the current target.

Keywords

drake_plan() understands special keyword functions for your commands. With the exception of target(), each one is a proper function with its own help file.

Examples

try(id_chr()) # Do not use outside the plan.
## Not run: 
isolate_example("id_chr()", {
plan <- drake_plan(x = id_chr())
make(plan)
readd(x)
# Dynamic branching
plan <- drake_plan(
  x = seq_len(4),
  y = target(id_chr(), dynamic = map(x))
)
make(plan)
readd(y, subtargets = 1)
# Static branching
plan <- drake_plan(
  y = target(c(x, .id_chr), transform = map(x = !!seq_len(4)))
)
plan
})
