In ddR: Distributed Data Structures in R

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")

## S4 method for signature '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.
