[R-sig-Geo] plotKML 'kml' function with raster input

[Gregovich, Dave P (DFG)]

Hello,
I am not able to create a .kml raster via the 'kml' function of plotKML (see the error below).
I am  setting the path to gdal in my windows registry as  'C:/Program Files/GDAL' -- the folder that contains 'gdalwarp.exe' and 'gdal_translate.exe' upon gdal installation.
I have also set the parameters in 'plotKML.env' in the two following ways (I don't know which it is supposed to be).
plotKML.env(gdalwarp = 'C:/Program Files/GDAL', gdal_translate = 'C:/Program Files/GDAL')
and
plotKML.env(gdalwarp = 'C:/Program Files/GDAL/gdalwarp.exe', gdal_translate = 'C:/Program Files/GDAL/gdal_translate.exe')


kml.folder <- 'c:/dave/temp';kml.file <- 'test.kml'
rast <- raster(extent(-135.2,-135.1,58.1,58.2),nrows=10,ncol=10,crs=CRS('+init=epsg:4326'))
rast[]<-rnorm(ncell(rast))
kml(rast,kml.fold,kml.file,colour = 'black')

#Results in the following messages...with no kml or kmz file output.
KML file opened for writing...
Writing to KML...
Closing  test.kml
Warning message:
In paths(show.paths = TRUE) :
  Could not locate GDAL! Install program and add it to the Windows registry. See http://www.gdal.org/ for more info.
