Now we compute the envelopes of the L-function based on simulations from the fitted model:
> swedenv <- envelope(swedfit, Lest, nsim=39, global=TRUE,
savepatterns=TRUE)
where we set savepatterns=TRUE to save the simulated point patterns for re-use in other calcu-
lations. The centred L-function is plotted in Figure 13.29 using the plo t formula.
