Create a netCDF File
Creates a new netCDF file on disk, given the variables the new file is to contain.
nc_create( filename, vars, force_v4=FALSE, verbose=FALSE )
filename |
Name of the netCDF file to be created. |
vars |
Either an object of class |
force_v4 |
If TRUE, then the created output file will always be in netcdf-4 format (which supports more features, but cannot be read by version 3 of the netcdf library). If FALSE, then the file is created in netcdf version 3 format UNLESS the user has requested features that require version 4. Deafult is FALSE. |
verbose |
If TRUE, then information is printed while the file is being created. |
An object of class ncdf4, which has the fields described in nc_open.

# Define an integer dimension

# Make an integer variable. Note that an integer variable can have
# a double precision dimension, or vice versa; there is no fixed
# relationship between the precision of the dimension and that of the
# associated variable. We just make an integer variable here for
# illustration purposes.
varPop <- ncvar_def("Pop", "count", dimState, -1,
longname="Population", prec="integer")
# Create a netCDF file with this variable
ncnew <- nc_create( "states_population.nc", varPop )
# Write some values to this variable on disk.
popAlabama <- 4447100
ncvar_put( ncnew, varPop, popAlabama, start=1, count=1 )
nc_close(ncnew)
