areaLoss(X, r, ngrid=spatstat.options("ngrid.disc"), subset=NULL)"ppp").ngrid * ngrid array of test points
that will be used to estimate the uncovered area.X
for which the area difference should be computed.X (or X[subset])
and one column for each value in r.X[i] in X
and for each radius r,
the area of that part of the disc of radius r centred at the
location X[i] that is not covered by any of the
other discs of radius r centred at the points X[j]
for j not equal to i.
This area is important in some calculations related to
the area-interaction model AreaInter. The result is a matrix, with one row for each point in X
and one column for each entry of r.
The area is calculated by discrete approximation, using an
ngrid * ngrid grid of test points.
