Species distribution modeling with presence-only data using log-Gaussian Cox process

Before messing with lgcp I'd look at spatstat - lgcp is more intended for
relative risk calculations where you have "cases" and "controls", and also
for
space-time data.

spatstat seems to have functions for fitting (and simulating) LGCPs to
point patterns so I think that might be what you are after...

A  way out of this may be to make a local copy of the lgcp sources,
remove the rpanel dependency from DESCRIPTION, and install it from
there. You won't get the functions that need rpanel, but those might not
be essential.

Thank you very much Edzer.

I tried to install lgcp, but I got an error message regarding BWidget.
I think that Bwidget is an external software and I don't know how to
install it in MacOS (Big Sur 11.2).

This is the error that I get when trying to install lgcp in R 4.0.3:

    Have you tried package lgcp?
