Calculate the area of a convex hull given its coordinates
Given the coordinates of a convex hull (i.e. a polygon), this function
calculates its area. Not intended for direct use outside of
siberConvexhull.
hullArea(x, y)
x |
a vector of x-axis data |
y |
a vector of y-axis data |
a scalar representing the area of the convex hull in units of
x * y; i.e. most commonly in permille squared for isotope data.
