Hi,
Does anyone has experienced issues using "extract" function from raster
Package using a cluster?
I want to make a simple extraction of pixels from rasters using a
multi-polygon shapefile.
I'm just doing something like:
beginCluster(20)
# Create list with raster filenames
my700.rasters <-
Is it possible to take advantage of multi-cores with function
rasterToPoints for converting a stack of several rasters into a x,y,z data
frame ?
Thanks,
Guillermo

} else {

Hi:
Is there any known issue on using writeRaster under Windows vs Linux?
I have been trying to write a rasterlayer as a geotif in a Linux
(centos) machine with no success...
I have this raster layer:
varTmpRaster
class : RasterLayer
dimensions : 720, 1440, 1036800 (nrow, ncol, ncell)
graphics grDevices utils datasets methods base
other attached packages:
[1] rgdal_0.8-16 raster_2.2-31 sp_1.0-15
loaded via a namespace (and not attached):
[1] grid_3.1.0 lattice_0.20-29

Hello:
I have been trying to plot a netcdf layer as a raster and have found one
single issue that I'd like know if I'm doing something wrong. If I use
normally be an optional bonus).
So what you could do is (a) write the data provider and (b) transform
the lon/lat values to the projection used, and use that to make a
raster.

Hi Robert:
Thank you

in other software such as GRASS or ArcMap and is still showing up with the

Thanks for any help with this.
