Rick, I had the same problem. Perhaps I simply misunderstood the
maptools function. I wrote the script below and that worked for me (it
includes all polygons). It probably has some limitations. Robert
polykml <- function(sw, filename, kmlname, namefield, kmldesc="Made with R" ) {
out <- s

Let me refine my request for help. I have a matern as per the code below. What
i want to do is to initialize the matern at point/distance zero to be equal to
1.1 not 1.0 as is at present. I would appreciate your help very much.
library(geoR)
curve(matern(x, phi= 1.0, kappa = 1.0),from
Rick, I wondered the same thing a while ago and wrote this script; I
worked for my purposes but never really finished it (e.g.
SpatialPoints objects support; and I wanted to add folders). Perhaps
you or someone else can finish it (or do a better one) and send it to
the maptools maintainers? Robert
Hello List:
I'm using R 2.9 on Windows XP/64 for this example, with recent builds of
maptools and rgdal packages.
The shape file used in this example can be obtained from:

While studying the example for kmlPolygon() in the maptools.
Hello all!
I've got a file with Lat/Lon organised in the following way:
NAME | LATp1 | LONp1 | LATp2 | LONp2 | ... | LONp4
Each row correspond to an area coveres by the satellite scene (4 LAT/LON
pairs).
Two things are important for my now:
1. I need the line in the middle of the polygo

Sorry about that, this is what I did:
