Examples

# First open the test NETcDF file.
filePath <- system.file("extdata", "tnc.nc", package = "hyfo")


# Then if you don't know the variable name, you can use \code{getNcdfVar} to get variable name
varname <- getNcdfVar(filePath)

nc <- loadNcdf(filePath, varname)

# Then write to your work directory

## Not run: 
writeNcdf(nc, 'test.nc')

## End(Not run)
