Subject: warning: size of values file does not match the number of cell
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
