I think this is a rather nice feature and hence I have updated the plot method in googleVis to use the RStudio viewer pane as the default output. If you use another editor, or if the plot is using one of the Flash based charts, then the browser is still the default display.
The behaviour can also be controlled via the option
options("viewer"=NULL)and googleVis will plot all output in the browser again.
Of course shiny apps can also run in the viewer pane. Here is the example of the
renderGvishelp page of googleVis. For more information about the new viewer pane see the online RStudio documentation.
For the time being you can get the next version 0.4.6 of googleVis from our project site only. Please get in touch if you find any issues or bugs with this version, or add them to our issues list.
