Capturing signals from within external libs
I have a continuous loop running in an external library that I am calling
from C (R API). This loop is processing events in real time with the
possibility of significant lag between events.
When processing an event, I can make use of R_CheckUserInterrupt, but
while the external library code is waiting on a new event, I don't have an
opportunity to call this - my entry points are only on

envelopes of simulations
Hello!
I am writing you because I could not plot the confidence envelopes for
functions Jest, Jcross, Jdot, Jmulti, and L, using the Spatstat package.
I have already understood how to do that for Kest or Jest, that is:
JEnv <- plot(envelope(PPPData, Jest))
Where PPPData is my ppp object.
However, for Jcross I must specify the two marks I want to analyse.
That is, usually I would get the Jcross doing:
Jc <- Jcross(PPPData,"Aun","Qsu")
For marks "Aun" and "Qsu".
For L...
