Hi Matt,

You can check if the file is OK by using the ncdump program.  ncdump
is one of the utility programs that comes with the netCDF
distribution.  A simple check would just use the "-c" option to just
dump the structure of the netCDF data and its coordinate variables (if
any), for example:

  ncdump -c /scratch/pocernic/int_fcst.20021201.0010.nc

If there are no errors emitted by ncdump, then the file is probably
fine.

I haven't used the R interface to access netCDF data, but doesn't the
read command require more arguments to specify which variable is being
read?  Something like:

  read.netCDF(aaa, name="dewpt")

although I don't know the right R syntax for providing a variable
name.  The R documentation contains no examples, so I can't be much
more help with using it ...
