I want to create a dataset in R with spatial correlation (i.e. clustering) built in for a linear regression analysis. Any tips on how to do this? Thanks.

The package 'spatstat' has functions for simulating several different kinds of spatial process. Hoping this helps, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding at manchester.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 18-Sep-08 Time: 00:06:48 ------------------------------ XFMail ------------------------------

Thank you for the input. Which command in the spatstat package am I looking for? The documentation is unclear to me.
Dear J.J.Harden I think that on spatial stat you will find several ways of simulate spatial pattern that (point or line) that may be what you are looking for. Case not, please let me know and may be we can improve some solution. Best wishes, miltinho astronauta brazil On Wed, Sep 17, 2008 at 7:36 PM, jjh21 <jjharden at gmail.com> wrote:

The original question was pretty opaque too. I think that the response from both the people who replied was based on your use of the word "clustering", which is most often used in spatial statistics with reference to the analysis of point patterns. Since that possibly isn't the case, perhaps you should reformulate your question, and consider posting on the R-sig-geo list, after reviewing the Spatial Task View on your nearest CRAN mirror. My guess would be that you are thinking of local indicators of spatial association using areal data, in which case there are some functions in the spdep package, but until we know what your actual needs are, it is hard to say. You could, for example, be looking for some of the tests in the DCluster package, but we cannot tell. Roger Bivand
