Description Usage Arguments Value Examples

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.

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

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

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

##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)
