Can voronoi polygons calculated in R be converted to ESRI shapefile?

Hi

 Thank you for your useful info.

 However for following statement,

voronoiShapefile <- function()
{

-----X8--------------X8-----------X8--

   for (i in seq(along=polys))
  {
      pcrds <-
cbind(tritest.vp[[8]][,1],tritest.vp[[8]][,2] )

I think all "8"s needed to "i" like this.

  cbind(tritest.vp[[i]][,1],tritest.vp[[i]][,2] )

  BTW, any method finding neightbour voronoi'cells' IDs?


 Regards.
