[gradsusr] using re() to regrid NARR

[Roberto Mera]

All,

I've been looking at the re() function in opengrads to regrid NARR to a 
0.25 deg grid. I have another file from regional model output in a 
completely different grid that I would also like to regrid. Can the re() 
function be used for non-global data? I got some errors before when 
trying to regrid the files. It would not let me subtract them from one 
another. I had tried something like:

  r25=re(tave,0.25)

and the same thing with the regional model.
