collectVector: Return a Distributed Vector to the Master Process

In bigGP: Distributed Gaussian Process Calculations

Return a Distributed Vector to the Master Process

Description

collectVector retrieves a distributed vector from the slave processes, reconstructing in the correct order on the master process. Objects can be copied from environments, lists, and ReferenceClass objects as well as the global environment on the slave processes.

Usage

collectVector(objName, objPos = '.GlobalEnv', n, h = 1)

Arguments

objName	an object name, given as a character string, giving the name of the object on the slave processes.
objPos	where to look for the object, given as a character string (unlike get). This can indicate an environment, a list, or a ReferenceClass object.
n	a positive integer, the length of the vector.
h	a positive integer, the block replication factor, h, relevant for the vector.

Value

collectVector returns a vector of length, n.

## Not run: 
bigGP.init(3)

x <- rnorm(n)
distributeVector(x, 'tmp', n = n)
y <- collectVector('tmp', n = n)
identical(x, y)
