At least libgdal-dev and libproj-dev are missing. You can have a look at

to do quite a bit more).

Dear all,
Thank you everyone. The issue (as pointed out) is the following;
# [1] "vobjtovarid4: WARNING I was asked to get a varid for
dimension named number_of_pixels BUT this dimension HAS NO DIMVAR! Code
will probably fail at this point"
I have contacted the VIIRS people and will ke
This is very helpful - thank you!

You won't find much on this kind of file in the R community, this is
relatively new NetCDF-4 with "groups", and contains a satellite "granule" -
a kind of pre-mapping raw data array with only technical information about
where the scanning occurred.
In short, raster and stars package (and RNetCDF a
Hi,
I'm testing a package using travis and I keep getting an error message
about rgdal not being found or executable. I've been trying to piece
together things I've found online but to no avail.

Dear Millu,
The data they use is not with the CRS set, so the displayed result is showing
the grid points (extent: 0.5, 4064.5, 0.5, 3232.5). Then you should consult the
VIIRS data guide so that you can organize your data, to which you need to know
the start data for both latitude and longitude
Hi Miluji,
the R in general do not handle very well with netCDF. However I
recommend you use the netcdf4 package before try others.
This link is a good start:
