[R-sig-Geo] allocate error Kenv.csr()

[Marco Helbich]

Dear List,

I want to calculate envelopes of Khat from simulations of csr with the 
Kenv.csr(splancs) function. My dataset contains around 300 cases. Using the 
Kenv.csr function (testing only 3 simulation runs) I got following error 
message:

> UL.khat <- Kenv.csr(pts.dat, stadtreg.pol, nsim=3, s)
Doing simulation  1
Fehler: kann Vektor der Größe 2.2 MB nicht allozieren
Zusätzlich: Es gab 50 oder mehr Warnungen (Anzeige der ersten 50 mit 
warnings())

Enclosed please find the output from the sessionInfo(), traceback() and 
gc():
