Given rect code, find area or proption rect area within a perimeter.

Description

Given rect code, find area or proption rect area within a perimeter.

Usage

r_within_peri(r, peri, valueOut = "p", scale = "nmi")

sr_within_peri(sr, peri, valueOut = "p", scale = "nmi")

mr_within_peri(mr, peri, dlat = 5, dlon = 10, valueOut = "p", scale = "nmi")

dr_within_peri(dr, peri, dlat = 1, dlon = 2, valueOut = "p", scale = "km")

Arguments

r, sr, mr, dr	Rectangle codes for different types of rects.
peri	Perimeter e.g. demarcating geographical distribution of fish.
valueOut	If "p" (the default) return proportion, else if "A" return area.
scale	If valueOut is "area", "nmi" returns area in square nautical miles, otherwise "km" in square kilometers.

Note

Not yet robust against rectangles outside the given perimeter. Destined for package geo?
