Hey, You need to transform the K function as follows Ks<-Kest(object.ppp, border,r=seq(0,5, by=1000)) plot(Ks$r, sqrt(Ks$border/pi)-Ks$r) if you choose border correction. Hope that's stuff will make it Best regards Alex P.S.: for a confidence enveloppe, you can use aleatoire<-runifpo

Hi. I need some help for plotting L(r) and Lcross so that I can have my confidence interval(CI) parallel to X axis. The plot I have obtain so far the graphic is not horizontal, then it is difficult to interpret strong the aggregation is or the attraction. thanks ___
