as.dlist: Creates a distributed list from the input.

Description

Creates a distributed list from the input.

Usage

as.dlist(items, nparts = NULL)
as.DList(items, nparts = NULL)

Arguments

items

The object to convert to a dlist.

nparts

The number of partitions in the resulting dlist.

Value

A dlist converted from the input. Note that a list of partitions (resulting from the use of parts()) may be used with as.dlist. This will recombine those partitions into a single distributed object.
