When no domain is specified it infers it from the data range. Since it doesn't know you're trying to model a detection function it doesn't fix the left boundary point to zero; it's like any other 1D point process on an arbitrary interval. The solution needs to be to explicitly specify the domain for the distances.
I added a "domain=" parameter to the lgcp function. We have to adjust the practicals accordingly!
A little unclear what the integration range is that's used in the following model (no spatial process specified, just fitting detection function):
Note that adding 100 to all the distances does something to increase the max distance? But maybe also does something in terms of left truncation too:
Plots for these (note x and y axis limits):
(Note the left truncation stuff isn't trivial and there are a couple of ways of dealing with it.)
