stable.apply: Apply with Stable Dimensions

Description

Does the same thing as apply except that when the function returns a vector, the dimensions are put back the way they started.

Usage

stable.apply(X, MARGIN, FUN, ...)

Arguments

X

same as in apply.

MARGIN

same as in apply.

FUN

same as in apply.

...

same as in apply.

Value

• When FUN returns a scalar or when MARGIN has a length that is not one less than the number of dimensions in X, then the same as apply.

  Otherwise, an array similar to the result of apply, but with the dimensions permuted to correspond to the dimensions of X.
