Hi all,

I'm keen to use the gstat feature 'polylines' (appendix B in 
http://www.gstat.org/gstat.pdf) to restrict the point sample selection 
to within a polygon. That is, when undertaking localised kriging at a 
grid cell, samples are only used in the estimation if a line between the 
sample and grid cell does not cross a polygon boundary. The polylines 
feature appears to be implemented within the c-code for gstat 
(polygon.c) but I cannot find any means to use it within R-gstat nor any 
mention on lists. Any tips would be most welcome.
