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

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.

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?

ncdf4: Why are NAs converted to _FillValue when saving?
Dear all
I'm a newbie regarding netcdf data. Today I realized that I maybe do not understand some basics of the netcdf. I want to create a *.nc file containing three variables for Switzerland. All data outside of the country are NAs. The third variable is calculated from the first two variables. Basically there is no problem to do that. I copy the file with the data of the first variable,

Hi All,
I am trying to install ncdf package on a Linux 64-bit machine.
I successfully installed netcdf using this command,
./configure --prefix=/home/challar/netcdf/ --disable-netcdf4

Anyone understand this Climate Change article?
http://www.abc.net.au/unleashed/3699540.html
I'm supposed to write a Letter to the Editor to express my point of view and I should have a clear intention.
My only trouble is having an intention and a point of view as I don't get that article at all.
It's like written in gibberish.
Can anyone please explain to me what it is about?
Why am I so dumb in English..
Thanks in advance :)

Climate data logger ... !

Before I give up and install windows on my HD as well :-)
Maybe there is a solution.
The program to read the sampled data in the data-logger can be installed and started using WINE without problems. But the driver (which is installed separately) which allows the Data-logger to be recognised by the program on the USB port, cannot be installed.

doubt in climate variability analysis in R!
Hello all,
I am trying to use "clim.pact" package for my work, but since this is the beginning for me to use gridded datasets in "R", I am having some trouble.
I want to do seasonal analyses like trends, anomalies, variograms, EOF and probably kriging too to downscale my 1 degree gridded data to 0.5. So, as a first step, I compiled my entire dataset (with 25

where to ask questions regarding package=ncdf?
Should one ask questions relating to the R package 'ncdf' here? or
look for a more netCDF-oriented (but probably less R-oriented) list?
Why I ask:
I'm relatively new to R, which I've only used in the past for graphics.
I'm trying to learn R as an alternative to manipulating netCDF files
with NCO (which works well but lacks all the other R goodnesses). Hence
I've got a
