I have not used Grads before, still i was able to read in the control
file and get the basic info.! but, i am not sure about the package
required for .grd files in R - will i be able to read a Grads grid file
into R???
I am afraid there is no direct solution at this time in R. Perhaps the
following script can help converting the data?

Hope this helps,
Rainer
Thank u all,
