Bind pipelines

Bind two pipelines together by concatenating their steps. If both pipelines have steps with the same name, the step names of the second pipeline will be automatically adapted to avoid name clashes.

Usage

pip_bind(x, y)

Arguments

x

A pipeflow pipeline object.

y

A pipeflow pipeline object.

Value

A new pipeflow pipeline object representing the bound pipelines.

Examples

a <- pip_new("a") |>
  pip_add("prep", \(x = 1) x * 2) |>
  pip_add("fit", \(x = ~prep) x + 10)

# "prep" exists in both pipelines; the one from b gets a numeric suffix
b <- pip_new("b") |> pip_add("prep", \(x = 5) x * 3)

ab <- pip_bind(a, b)
ab[["step"]] # "prep", "fit", "prep2" (step name conflict auto-resolved)
#> [1] "prep"  "fit"   "prep2"
ab
#> <pipeflow_pip> a-b (3 steps)
#> ----------------------------
#>     step depends    out state
#> 1:  prep         [NULL]   new
#> 2:   fit    prep [NULL]   new
#> 3: prep2         [NULL]   new
