setCluster function

Define a parallel cluster object to be used in internal functions

This function defines a object that is placed in a relevant internal environment defined in faoutlier. Internal functions will utilize this object automatically to capitalize on parallel processing architecture. The object defined is a call from parallel::makeCluster(). Note that if you are defining other parallel objects (for simulation designs, for example) it is not recommended to define a cluster.

setCluster(spec, ..., remove = FALSE)

Arguments

• spec: input that is passed to parallel::makeCluster(). If no input is given the maximum number of available local cores will be used
• ...: additional arguments to pass to parallel::makeCluster
• remove: logical; remove previously defined cluster object?

Examples

## Not run:

#make 4 cores available for parallel computing
setCluster(4)

#' #stop and remove cores
setCluster(remove = TRUE)

#use all available cores
setCluster()
## End(Not run)
