do_dmapply: Backend-specific dmapply logic. This is a required override for all backends to implement so dmapply works.

Description

Backend-specific dmapply logic. This is a required override for all backends to implement so dmapply works.

Usage

do_dmapply(driver, func, ..., MoreArgs = list(), output.type = "dlist",
  nparts = NULL, combine = "default")
## S3 method for class 'ParallelddR,`function`':
do_dmapply(driver, func, ...,
  MoreArgs = list(), output.type = c("dlist", "dframe", "darray",
  "sparse_darray"), nparts = NULL, combine = c("default", "c", "rbind",
  "cbind"))

Arguments

driver

The driver that the logic dispatches on.

func

The function to execute

...

Iterable arguments from dmapply.

MoreArgs

A list of more arguments to the funciton.

output.type

The type of output (can be 'dlist', 'darray', 'sparse_darray', or 'dframe').

nparts

A 2d-vector indicating how the output is partitioned.

combine

One of 'default', 'rbind', 'cbind', or 'c', which specifies how the results from each partition should be combined.

Value

• An object specific to the backend, with the nparts and psize fields filled.
