[R-sig-Geo] Can you query points with a polygon?

2006-12-12 Thread Pierce, Ken
If I have a set of points from a shapefile (or generated in R) and a polygon from a shapefile, can I use the polygon to select the points that fall within it? One of the many packages must do it but I can't seem to figure which one. Thanks, Kenneth B. Pierce Jr. Research Ecologist Landscape Ecolo

[R-sig-Geo] Can you krige with a nominal response variable

2006-12-06 Thread Pierce, Ken
Is there a method for kriging a response with multiple states, for instance vegetation class in 10 classes? I know indicator kriging would work for a boolean variable. Is there an extension for multiple responses? Kenneth B. Pierce Jr. Research Ecologist Landscape Ecology, Modeling, Mapping and
