[R-sig-Geo] Other kernels for density.psp (spatstat)?

[Zev Ross]

Hi All,

I'm just wondering if anyone has used alternate kernel functions in 
density.psp from spatstat. The generic density function from stats, of 
course, allows for the use of several different kernel functions 
(triangular, biweight etc). I'm interested in applying kernel density 
estimation to lines (a road network) which density.psp is well-suited 
for, but that function is limited to the Gaussian kernel. Has anyone 
developed code to do this?

Thank you! Zev
