Hi Hernan,

The file you are trying to make is violating size constraints imposed
by the netcdf library/R interface, which is 2 GB in the R ncdf
package. To get around this switch to the R ncdf4 package, which is
the replacement for the ncdf package (I stopped supporting the ncdf
package in 2010) and set force_v4=TRUE in the nc_create() call. This
requires a modern version of the netcdf library to be installed on
your machine, which it probably is, since the netcdf version 4 library
has been out for many years now.

Regards,

--Dave
