In RGLab/MAST: Model-based Analysis of Single Cell Transcriptomics

Apply a vectorized binary operation recycling over last dimension

Description

When x is an array of order K, and y is an array of order K-1, whose dimensions otherwise agree, apply FUN by recycling y as necessary over dimension K of x.

Usage

applyFlat(x, y, FUN = "-")

Arguments

x	array, order K
y	array, order K-1
FUN	vectorized binary operation

Value

array, order K equal to FUN(x,y)

Examples

##Dumb example, could be done with scale(...,scale=FALSE)
x0 = matrix(1:10, nrow=2)
y0 = rowMeans(x0)
dim(y0) = c(1, 2)
x1 = MAST:::applyFlat(x0,y0)
stopifnot(rowMeans(x1)==0)
