This is probably completely off topic. But I get the impression the spatstat package has turned into a super-package. Which is likely to be difficult to maintain. Wouldn't a better result be achieved by freezing work on the package, and creating some smaller packages with a more specific focus, t

Hi, I have the coordinates of 3D points and I want to plot the pair correlation function of these points (https://en.wikipedia.org/wiki/Radial_distribution_function). I wonder if it possible to calculate this function with R. Maybe with the spatstat library? I tried but I found the way to do
