Binds two or more pipelines together by concatenating their steps. If the pipelines have steps with the same name, the step names of later pipelines are automatically adapted to avoid name clashes. A single pipeline is returned unchanged.
Usage
# S3 method for class 'pipeflow'
rbind(..., deparse.level = 1)Arguments
- ...
Two or more pipeflow pipeline objects.
- deparse.level
Not used, for compatibility with the generic
rbind().
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 <- rbind(a, b)
ab[["step"]] # "prep", "fit", "prep2" (step name conflict auto-resolved)
#> prep fit prep2
#> "prep" "fit" "prep2"
ab
#> <pipeflow> a-b (3 steps)
