[R] Remove attribute from netcdf4 object

Dear all

For a model I need to combine several netCDF files into one (which works fine).
For better overview I'd like to delete/remove some of the attributes. Is
there a simple way doing this?

I'm using the package netcdf4, which creates an object of class(nc) =
"ncdf4". It seems that for earlier versions of netcdf objects, there
was the function att.delete.nc{RNetCDF}. But this functions returns the
following error, when applied to ncdf4-classes:
Error: class(ncfile) == "NetCDF" is not TRUE

Thanks a lot for any help.

Kind regards

Raphael Felber

[R] Remove attribute from netcdf4 object

Dear Marc

Thanks for your remark. I don't want to use both packages. I mentioned the
package RNetCDF to show that there is a similar function I' d like to use.

[R] Remove attribute from netcdf4 object

Hi Marc

That's a workaround I can use. Thanks. I'm a newbie regarding netCDF
data. Is there any information I'm losing when switching between the
packages?

Betreff: Re: AW: [R] Remove attribute from netcdf4 object

ok. Sorry, I didn't understood good.
I don't think you can do it in ncdf4 functions. The only solution would be
to open it in RNetCDF, delete the attribute, save it and then open it in ncdf4.
