Look at the package ncdf4. You can use an OPeNDAP URL in place of the file name to perform subsets., -Roy> On Sep 27, 2016, at 9:06 AM, Debasish Pai Mazumder <pai1981 at gmail.com> wrote: > > Hi all, > > I would like to access and subset following OpeNDAP files. > server: > http://nomads.ncdc.noaa.gov/thredds/dodsC/modeldata/cfsv2_forecast_ts_9mon/2014/201404/20140403/2014040312/ > > file name: tmax.01.2014040312.daily.grb2 > <http://nomads.ncdc.noaa.gov/thredds/dodsC/modeldata/cfsv2_forecast_ts_9mon/2014/201404/20140403/2014040312/catalog.html?dataset=modeldata/cfsv2_forecast_ts_9mon/2014/201404/20140403/2014040312/tmax.01.2014040312.daily.grb2> > I would like to access and subset the file.
