Hi, I have a large raster file (netcdf) that I am trying to process ie
> bathr class : RasterLayer dimensions : 10800, 21600, 233280000 (nrow, ncol, ncell) resolution : 0.01666667, 0.01666667 (x, y) extent : -180, 180, -90, 90 (xmin, xmax, ymin, ymax) coord. ref. : NA data source : /work/up/common/bathymetry/ETOPO1/ETOPO1_Ice_c_gmt4.nc names : z values : -10803, 8333 (min, max) zvar : z Processing this with aggregate() gives the following warning: > min.bath <- aggregate(bathr,fact=out.agg,fun=min,expand=FALSE) Warning message: In .rasterFromRasterFile(grdfile, band = band, objecttype) : size of values file does not match the number of cells (given the data type) What does this warning mean? I've seen previously on the list that there was a bug associated with this warning - the message has only appeared for me since upgrading from about raster 2.0-12 (can't remember the exact version, unfortunately) to 2.0-31. Best wishes, Mark _______________________________________________ R-sig-Geo mailing list R-sig-Geo@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-geo
