SpatialGridDataFrame to netcdf grid

Then the fallback is to write a GTiff, and use gdal_translate to convert
it (one of the gdal utilities that build with the GDAL shared
object). If the same problem occurs, you may need to install netCDF and
GDAL from source. If that doesn't resolve it, then you'll need to
reshape the data to the required format and use functions in the ncdf
package to create and write to the file.

I found out that the Debian packages with the gdal_translate binary is
gdal-bin, and trying to writeGDAL() to GTiff and then gdal_translate as
suggested earlier gives the same error message about cdfid not being
valid.

Just so I understand how the SpatialGridDataFrame object is structured:

R> gridparameters(locs.sub.ts)
  cellcentre.offset cellsize cells.dim
1            -69.12  0.06109       113
2             63.64  0.03424       122
R> bbox(locs.sub.ts)
             min    max
coords.x1 -69.15 -62.25
coords.x2  63.62  67.80

How are the data (e.g. z values) aligned with respect to these values?  I
would like to know what as.data.frame(locs.sub.ts) returns: the
coordinates and data for the midpoint of the cell, or the data for some
other reference point in the cell.  Thanks again for any help.
