Details
Estimates the O-ring function proposed by Wiegand and Moloney (2004). The O-ring statistic is defined as:
O(r) = \lambda * g(r)
Generally speaking, O(r) scales the pair correlation g(r) function with help
of the intensity \lambda. One advantage of the O-ring statistic is that
it can be interpreted as a neighborhood density because it is a probability density
function (Wiegand & Moloney 2004, 2014).
Returns an 'Function value object' of the spatstat package.
