Hello I am trying read  nc rainfall  files directly from the UK centre for
hydrology and ecology website -
hourly:about 300Mb
https://catalogue.ceh.ac.uk/datastore/eidchub/fc9423d6-3d54-467f-bb2b-fc7357a3941f/
and daily about 90Mb
https://catalogue.ceh.ac.uk/datastore/eidchub/2ab15bf0-ad08-415c-ba64-831168be7293/precip/

I can download them "by hand" no problem using the ncdf4 package but
there's lots and I wanted to streamline the process

code I've used (which works for "by hand" downloading) is (for example)

nc_data<-nc_open("
https://catalogue.ceh.ac.uk/datastore/eidchub/2ab15bf0-ad08-415c-ba64-831168be7293/precip/chess-met_precip_gb_1km_daily_19610301-19610331.nc
")

However, when I run this I don't get an error message but R just sits there
with the little red circle (at least 30 minutes for the 90Mb files)

What I'm wondering is two things - a)is the data in fact downloading but
it's just taking ages and I need to let it run and go and have a coffee
                                                   b)is there (I can't find
anything) within R which allows me to monitor the progress of the download,
if in fact it is taking place?
Thanks Nick Wray
