[R-sig-Geo] functions on kernel density estimation in pointpattern analysis

[Dan Putler]

Hi All,

To add some detail to Roger's earlier, post density.ppp in the  
spatstat seems to be a very good answer to the original post since it  
is specifically designed to estimate a kernel density for a point  
process pattern. This function use a bivariate Gaussian smoother that  
lends itself to user configuration.
