Re: [R-sig-Geo] Filtering a set of points in a "ppp" object by distance using marks

Hi Marcelino, Thanks so much, I just make a little change in your code: ddd <- nndist(insects.ppp, by=factor(insects.ppp$marks)) subset(insects.ppp,  marks=="termiNests" & ddd[,"antNests"] >20) I put `ddd[,"antNests"] >20` despite `ddd[,"termiNests"] >20` because I need "termiNests" mark far

Sorry, I meant to say subset(insects.ppp, marks=="termiNests" & ddd[,"antNests"] >20) El 16/09/2020 a las 9:18, Marcelino de la Cruz Rot escribió: Hi Alexandre, may be this? ddd <- nndist(insects.ppp, by=factor(insects.ppp$marks)) subset(insects.ppp,  marks=="termiNests" &

[R-sig-Geo] Filtering a set of points in a "ppp" object by distance using marks

Dear R-Sig-Geo Members, I'd like to find any way to filtering a set of points in a "ppp" object by minimum distance just only between different marks. In my example: #Package library(spatstat) #Point process example - ants data(ants)
