Tight in RStudio viewer

I have updated the plot to the latest V2.0.3 because they say you can now have interactive plots in the TV viewer without posting them on your website. When I run the plot, nothing appears in the viewer, but if I click show in a new window in the viewer, it opens in the web browser. Any ideas why it won't display directly in the Rstudio viewer? Their demo shows that it should be here: https://plot.ly/r/offline/?campaign_id=open_source_dec2015&utm_source=Plotly+Community&utm_campaign=59ccfcd224-Open_Source_Announcement_General_Campaign12_mut_2015&mccutium=Campaign12_mut_2015&m97terium=campaign12_mut_2015&m97terium=campaign12_9
