I want to use R package SPARQL to run set of INSERT queries to a Virtuoso endpoint. How to give username and password to the function and which url to be used? When I tried
tmpRes=SPARQL('myserver:8890/sparql',update=updateQry)
I got error: Error: SPARQL Request Failed
I think you want:
tmpRes=SPARQL('http://dba:dba@myserver:8890/sparql', query=updateQry)
note both changes.
