pip_collect_out: Collect step outputs

In pipeflow: Fast Interactive Data Analysis Pipelines

Collect step outputs

Description

Returns the outputs of all pipeline steps as a flat named list keyed by step name. Use pip_view() to narrow the selection before collecting, and compose calls if grouped output is needed.

Usage

pip_collect_out(x)

Arguments

x	A pipeflow pip or view.

Value

A named list of outputs, one element per step.

Examples

p <- pip_new() |>
  pip_add("load", \(x = 1) x, tags = "io") |>
  pip_add("clean", \(x = ~load) x + 1, tags = "io") |>
  pip_add("model", \(x = ~clean) x * 2, tags = "model")
pip_run(p)

# Flat named list with one entry per step
pip_collect_out(p)

# Combine with pip_view to collect output for specific tags
grouped <- list(
  io = pip_view(p, tags = "io") |> pip_collect_out(),
  model = pip_view(p, tags = "model") |> pip_collect_out()
)
grouped
