Subject: [Rnomads-user] handling ReadGrib errors in batch
Message-ID: <CACxgkSCXYjCJEtjhm2VeaGWGMaVMzrfPO7LtqVX+1q5G9EzFSQ@mail.gmail.com>

Hello everybody,

I am using the rNOMADS package to work with GFS grib files. I run a R
script in batch, using Rscript.

As long as the file exists (and at least one combination of variable/level
exists), everything goes smoothly.

But when the file does not exist (or the only variable/level requested does
not exist) an error occurs and the script stops. I would like to use this
script for an operative purpose, so obviously I have to find a way to deal
with this in batch.

I tried using tryCatch but got not results.

Did anyone have this problem before?

Thanks!!

Best regards,
Solange

Hi Solange,

Can you provide the script, so we can see exactly what you're experiencing?

Thanks,


Danny
