Plot hex coverage for a given eccentricity

Plot hex coverage (number of intersecting ellipses) for a given eccentricity.

plot_coverage(proj, eccentricity = 0.9, n_ell = 20, return_type = 1)

Arguments

proj	object of class rmapi_project.
eccentricity	eccentricity of ellipses, defined as half the distance between foci divided by the semi-major axis. We can say \(e = sqrt{1 - b^2/a^2}\), where \(e\) is the eccentricity, \(a\) is the length of the semi-major axis, and \(b\) is the length of the semi-minor axis. Eccentricity ranges between 0 (perfect circle) and 1 (straight line between foci).
n_ell	number of points that make up an ellipse.
return_type	format of return object: 1 = a gridExtra object, 2 = a list of ggplot2 objects.
