Dear all, I'm trying to fit point pattern using spatstat and thomas.estK command for distances r (0,50) but default values are only 0,25. Can I change this values and try to fit for all range of distances. fitt_pp <- thomas.estK(abal.ppp, c(kappa=10, sigma2=0.1), *rmin* = NULL, *rmax* = 50) /Error in mincontrast(K, theoret, startpar, ctrl = list(q = q, p = p, rmin = rmin, : rmax= 50 exceeds the range of available data = [ 0 , 25 ]/ -- View this message in context: http://r-sig-ecology.471788.n2.nabble.com/fitting-point-pattern-using-spatstat-tp7577627.html Sent from the r-sig-ecology mailing list archive at Nabble.com.

Dear Marcelino, thanks a lot for the replay, It is work very well now. also an answer to the question of Rolf Turner, I will use this method to fitting point pattern of the forest stand plots, and analyze changes in model parameters over time. according to the some publications a lot of authors calculate maximum distance of the r value like 1/2 of the shortest plot dimension, in my case it is 50 m. Course may have to be taken into account edge effect. I am only have the problem how big segment can take, when I use smaller segment then I have a regular schedule at short distances. <http://r-sig-ecology.471788.n2.nabble.com/file/n7577631/fitt_pp.png> -- View this message in context: http://r-sig-ecology.471788.n2.nabble.com/fitting-point-pattern-using-spatstat-tp7577627p7577631.html Sent from the r-sig-ecology mailing list archive at Nabble.com.
