In RBigData/pbdSHAQ: Tools for Tall Distributed Matrices

Description

Centers and/or scales the columns of a distributed matrix.

Arguments

x	A shaq.
center	logical value, determines whether or not columns are zero centered
scale	logical value, determines whether or not columns are rescaled to unit variance

Value

A shaq.

Communication

The communication consists of two allreduce calls, each quadratic on the number of columns.

library(kazaam)
x = ranshaq(rnorm, 10, 3, mean=30, sd=10)

x
scale(x)
