Hi, What is the exact error you get? Can you provide a example that reproduces the problem? What kind of system are you running (sessionInfo() output). An idea: The documentation of write.asciigrid says that the variable x (in this case sn8.interpold) should be a SpatialGridDataFrame. Does

Hi, I have a SpatialLinesDataFrame (A) and a SpatialPointsDataFrame (B). How can I establish which points in B are to the east of a given line in A? The problem is to figure out which persons (whose addresses are geocoded in B) have addresses to the east of a given road (whose coordinates are

2008-10-10 Thread Edward Schnitzke
Hello, I've recently begun working with the geoRglm package. I'm a relative novice in spatial statistics and modeling, and I fear I may be missing something horribly, thereby doing something dangerous. In reading the documentation and working through a few tutorials and examples, I am unclear
