pFlowClust: Parallelized FlowClust

Description

A parallelized call to flowClust via the snow package and framework. Not called by the user.

Usage

pFlowClust(flowData,cl, K = 1:15, B.init = 100, tol.init = 0.01, tol = 1e-05, B = 1000, randomStart = 50, nu = 4, nu.est = 1, trans = 1, varNames = NA)

Arguments

flowData

The data object, must be a flowFrame, flowSet or list of flowFrames

cl

The snow cluster object

K

The number of clusters to try for each flowFrame. Can be a vector. This is what is parallelized across processors.

B.init

See flowClust documentation

tol.init

See flowClust documentation

tol

See flowClust documentation

B

See flowClust documentation

randomStart

See flowClust documentation

nu

See flowClust documentation

nu.est

See flowClust documentation

trans

See flowClust documentation

varNames

See flowClust documentation

Value

Returns a list of lists of flowClust objects The outer list corresponds to the flowFrames passed into the method. The inner list corresponds to the K cluster solutions passed into the method, for each flowFrame (ie If the input is a list of two flowFrames, and K=1:10, then the result is a list of length 2. Each element of the list is itself a list of length 10. The kth element of the inner list is the flowClust k cluster solution.)

Details

Calls flowClust via the clusterMap method of the snow package. Parallelizes the computation of multiple components for a single flowFrame in a loop over multiple flowFrames. If the snow cluster is NULL, will make the call via mapply.
