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.

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)
