Surface Area of the Convex Hull
Description
Given a set of locations, this function determines the surface area of the convex hull (or envelope) of the set.
Usage
chull_area(x, y, geo = FALSE)
chullArea(x, y, geo = FALSE)
Arguments
x |
A vector of x (or longitude) coordinates. |
y |
A vector of y (or latitude) coordinates. |
geo |
A logical value indicating whether the locations are defined by
geographic coordinates (pairs of longitude/latitude values). If |
Value
A single numeric value corresponding to the surface area of the
convex hull (in square meters if geo
is TRUE
).
