netcdf read/write package

Hi everyone,

I'm looking for an R package that is capable of _write_ as well as read 
in netcdf format.  Could someone offer advice on this?

I have some data in netcdf format and I only need to make simple 
modifications to it.
I thought doing that via R could be handy and would save me reading up 
on C++/Fortran netcdf lib.

Thanks and regards,
viet nguyen
