I am looking for a way in R to extract netcdf files from a Thredds server using OpenDAP. When I type in a full path/filename to a file in open.nc() and read.nc() from the RNetCDF package I can access the file content, but how can I get a list of all available files/URLs on the server? In python there's apparently a function called "threddsclient.opendap_urls"() that do this, but I haven't found a similar function in R. Is there a way to do this?
