x	Target pipeflow pipeline object.
y	Source pipeflow pipeline object.
step	Step name to copy from y.

Value

The updated target pipeline, invisibly.

Examples

# Build a source pipeline with reusable steps
src <- pip_new("source") |>
  pip_add("load", \(n = 3) seq_len(n)) |>
  pip_add("square", \(x = ~load) x^2)

# Copy steps into a new pipeline one at a time.
# The dependency of "square" on "load" is re-established automatically.
dst <- pip_new("target")
pip_add_from(dst, src, "load")
pip_add_from(dst, src, "square")
pip_run(dst)
