Hi,
Can anybody help me a little on how to transfer values from a data frame
(coord.x, coord.y, value) to
a raster file. I have a raster initialized to 0 values and I want to
substitute zeros for the specific values
at coord.x and coord.y
Thank you very much,

;- crop(r10kto1k, extent.r1k)
r1k.masked <- mask(r1k, r10kto1k)
}

Dear listers,
Can anybody help me with this ?
How can I mask a 1km UTM grid raster with a list of coordinates
which represent the center of 10km UTM grid squa
SpatialPolygonsDataFrame representing 10km
UTM grid squares from a list of coordinates which represent their grid
center.
I will appreciate if you can give me some hints on how to do this.

Thank you very much Roger.
Still another question: Can you plot a polygon shapefile with borders
but transparent interiors ?
