[R-sig-Geo] Kernels in spatstat for lines

Hi All,

Sorry, I thought I'd try my question one more time, hoping that someone 
could give me some guidance. I'm wondering if anyone has used alternate 
kernel functions in  density.psp from spatstat. The generic density 
function from stats 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 or can anyone provide guidance?

Thank you in advance, Zev
