[R] How to use rfm.test ? (Package MarkedPointProcess)

I would like to compute the MC test (rfm.test) available in the package MarkedPointProcess (for the data BITOEK for example) in order to test the dependence between the marks and their locations. Why the syntax of rfm.test is false here? I have the message :



ML WARNING! Forbidden values! -- if there are too many warnings try narrower lower and upper bounds for the variables. -9.802347e-17 1364.372 [ 0 0.01808660 , 9.990131 1364.372 ]

The program :



# Packages #

library(spatstat)
library(RandomFields)
library(adapt)
library(MarkedPointProcess)


# Program #

data(BITOEK)
win <- ripras(steigerwald$coord)
PointProcess <- ppp(x=steigerwald$coord[,1],y=steigerwald$coord[,2],window=win,marks=steigerwald$diam) plot(PointProcess)

rfm.test(coord=steigerwald$coord,steigerwald$diam,MCrepetitions=19)


regards.
