as.vector: Distributed object to Vector Converters

Description

Converts a distributed matrix into a non-distributed vector.

Usage

as.vector(x, ...)

# S4 method for ddmatrix as.vector(x, mode = "any", proc.dest = "all")

Arguments

x

numeric distributed matrix

...

Additional arguments.

mode

A character string giving an atomic mode or "list", or (except for 'vector') "any".

proc.dest

destination process for storing the matrix

Value

Returns an ordinary R vector.

Details

The proc.dest= argument accepts either the BLACS grid position or the MPI rank if the user desires a single process to own the matrix. Alternatively, passing the default value of 'all' will result in all processes owning the matrix. If only a single process owns the undistributed matrix, then all other processes store NULL for that object.
