Invoke a computation on a view of some data set and return the result

Source: R/adapters.R
adapter.Rd

This function creates an adapter pattern that allows running a computation on a view of the data and copying the results back to the original dataset.

Usage

adapter(
  daf,
  computation,
  input_axes = NULL,
  input_data = NULL,
  capture = memory_daf,
  output_axes = NULL,
  output_data = NULL,
  empty = NULL,
  relayout = TRUE,
  overwrite = FALSE
)

Arguments

daf

A Daf object to adapt

computation

A function that takes a DafWriter and performs computations on it

input_axes

Optional named list specifying axes to expose as input

input_data

Optional named list specifying data to expose as input

capture

Function to create a capture Daf (default: memory_daf)

output_axes

Optional named list specifying axes to expose as output

output_data

Optional named list specifying data to expose as output

empty

Optional named list mapping data keys to values for filling missing data

relayout

Whether to allow relayout when copying results (default: TRUE)

overwrite

Whether to overwrite existing data when copying results (default: FALSE)

Value

The result of the computation function
