[R-sig-Geo] plotKML kml_layer.Raster problem

[Frede Aakmann Tøgersen]

Hi Andreas

Can you provide a small example showing the details of what you're trying to do. I don't think that anyone can help you with the little information you have given.

If you do not have any example please show us the output from traceback() immediately after the error.

I don't think this has anything to do with NA's in your data values as I don't get any errors doing this (from man of kml_layer.Raster):


data(eberg_grid)
library(sp)
coordinates(eberg_grid) <- ~x+y
gridded(eberg_grid) <- TRUE
proj4string(eberg_grid) <- CRS("+init=epsg:31467")
data(SAGA_pal)
library(raster)
r <- raster(eberg_grid["TWISRT6"])

## Put some NA's into data
r at data@values[1:10] <- NA

kml(r, colour_scale = SAGA_pal[[1]], colour = TWISRT6) 


 

Yours sincerely / Med venlig hilsen
