Functions to split an AffyBatch, a list of files and a matrix into several objects for distributed computing. If possible objects will be of the same size.
splitAffyBatch(abatch, number.part) splitFileVector(FileVec, number.part) splitMatrix(matrix, number.part)
abatch |
An object of class AffyBatch. |
FileVec |
A character vector containing the names of the files. |
matrix |
An object of class matrix. |
number.part |
Number of parts to split the object |
