coo_up: Retains coordinates with positive y-coordinates

Description

Useful when shapes are aligned along the x-axis (e.g. because of a bilateral symmetry) and when one wants to retain just the upper side.

Usage

coo_up(coo, slidegap = FALSE)

Value

a matrix of (x; y) coordinates or a Coo object (Out are returned as Opn)

Arguments

coo

matrix of (x; y) coordinates or any Coo object.

slidegap

logical whether to apply coo_slidegap after coo_down
