Hi,
I'm having a problem with my shiny app.
Suddenly the plots stop working and I get this error:
Warning: Error in : invalid assignment for reference class field ‘language’, should be from class “character” or a subclass (was class “NULL”)
Can you please help me to understand what is the problem?
When I tried to ran it on a different computer it works.
the problem happens while using the function userTimeline in the twitteR package.
Thanks,
Sharon
