Description

Change the keepOut flag at a given pipeline step, which determines whether the output of that step is collected when calling pipe_collect_out()⁠after the pipeline was run. See column⁠keepOut' when printing a pipeline to view the status.

Usage

pipe_set_keep_out(pip, step, keepOut = TRUE)

Arguments

pip	Pipeline object
step	string name of step
keepOut	logical whether to keep output of step

Value

the Pipeline object invisibly

Examples

p <- pipe_new("pipe", data = 1)
pipe_add(p, "add1", \(x = ~data, y = 1) x + y, keepOut = TRUE)
pipe_add(p, "add2", \(x = ~data, y = 2) x + y)
pipe_add(p, "mult", \(x = ~add1, y = ~add2) x * y)
p |> pipe_run() |> pipe_collect_out()

pipe_set_keep_out(p, "add1", keepOut = FALSE)
pipe_set_keep_out(p, "mult", keepOut = TRUE)
p |> pipe_run() |> pipe_collect_out()
