slice: Take a slice of an array selecting indices along a margin

In gmonette/gnew: New functions for spida2

Take a slice of an array selecting indices along a margin

Description

Performs the same role as selecting with subscripts except that this is easier to use when dimension of the array is not known. Its application is limited, however, to selecting single slices along a single dimension.

Usage

slice(a, MARGIN, ind)

Arguments

a	an array
MARGIN	a single dimension along which to select a slice (i.e. a section)
ind	the level at which to select the slice. If ind is out of range, slice returns NAs with the correct structure

Examples

Titanic
slice(Titanic, 1, 1)  
slice(slice(Titanic, 1, 1), 1, 2)
