Hi,

I am currently using R 2.5.1 on a linux
operating system (I am connected to the linux system via remote desktop
connection).   I am trying to estimate nuiscance parameters for a Geyer model that will be fit to a spatial point process dataset with ~10,000 points.  However, R reaches its vector allocation limit with the parameter ranges I have specified.  As a result, I will try estimate the parameters by subsetting the ppp dataset based on a grid of approximately 50x50km squares.  I understand how to subset ppp but I would like to find a simple way of producing my grid (or owins).  Can anyone suggest a command/have a section of code that would do this for me?  Thank you for your assistance with this issue and for your time.

Sincerely,





Honey-Marie Giroday, M.Sc. Candidate, A.Ag., B.I.T.
