     Read from or write to existing netCDF format files, or create new
     ones.

     The netCDF data file format from Unidata is a
     platform-independent, binary file that also contains metadata
     describing the contents and format of the data in the file. 
     NetCDF files contain one or more variables, which are  structured
     as regular N-dimensional arrays.  They also contain dimensions,
     which  describe the extent of the variables' arrays.  Data can be
     read from or written to variables in arbitrary hyperslabs.  The R
     package 'ncdf' allows reading from, writing to, and creation of
     netCDF files.  Note that the netCDF library must already be
     installed on your machine for this R interface to the library to
     work.

     If you are absolutely new to netCDF files, they can be a little
     overwhelming, so here is a brief sketch of what documentation you
     need to read next.  

     If you want to READ data  from an already-existing netCDF file,
     first call 'open.ncdf'  to open the file, then call 'get.var.ncdf'
     to read the data from the file.  

     If you want to WRITE data to a new netCDF file, first call
     'dim.def.ncdf' to define the dimensions that your data exists
     along (for example, perhaps latitude and longitude), then call
     'var.def.ncdf' to define a variable in the netCDF file that will
     hold your data, then call 'create.ncdf' to create the netCDF file,
     then call 'put.var.ncdf' to write your data to the newly created
     netCDF file.

     This is version 1.6 of the ncdf library.
