ncdf package problem - put.var.ncdf

Help asked for automated generation of ncdf variables
Hi,
I'm using the "ncdf" library for creating ncdf files.
But I need to create about 100 variables per file (e.g. single rivers),
So I do not like to create each variable separately.
Unfortunately I found no way to make this work, as I'm unable to create a
correct list of class "var.ncdf".

Can anyone please let me know how exactly ncdf deals with NaN.
I am trying to pass in a vector of data that has some NaN in it, into a variable in NetCDF.

Dear all,
I have a problem in writing a variable to a NetCDF-File.
My code works pretty well until the step put.var.ncdf():

missing values in 'ncdf', integer versus byte
I'm working with the ncdf package, and I'm seeing a behavior which I
am unsure whether it is a bug or a feature. I am creating a variable,
which I make with the precision of "byte" and also set a missing
value, When I put into this variable, all my NA values are put in
properly as the missing value. However, when I read it back, I get
the missing value rather than NA.
