[R-sig-Geo] grabriel graphs weighted by alternative distance measure

does not make sense for me. If anyone has an idea of how I might try and create Gabriel graphs based on a distance measure that is not Euclidean, I would love to hear it. Thanks in advance for everyone's help. I am currently using R (v.2.10.1) on Windows XP. Ilona Naujokaitis-Lewis, PhD s

Re: [R-sig-Geo] SGDF loop processing time

Dear Roger, and List-Serve, I am posting here a .RData file(IlonaQuesRgeo.RData) to help with my previous query (see original email below) as per Roger's request. Please let me know if the attachment does not work. Cheers, Ilona Ilona Naujokaitis-Lewis Centre for Applied Conserv

[R-sig-Geo] SGDF loop processing time

Dear List-serve, I have written a loop that creates a Spatial Grid Dataframe from 2 other SGDFs. I am interested in finding out if there is a way to decrease the processing time of the entire loop. I am aware that loops in R are not the most efficient way to go, but based on my knowledge, I a
