RStudio

Usage

To open a client in the embedded RStudio Viewer-tab call hgd_view() after starting the server:

library(httpgd)
hgd()
hgd_view()

To view a client in an external browser window call:

# hgd()
hgd_browse()

Troubleshooting

Sometimes (if the Viewer-tab is resized with any plot in the Plots-tab) RStudio will activate its own graphics device, the Plots-tab will obtain focus, and httpgd will show the message “Device inactive.” in the Viewer-tab.

The list of graphics devices (dev.list()) will look something like this:

> dev.list()
RStudioGD   agg_png    httpgd 
        2         3         4 

This can be easily solved by closing the current (RStudioGD) graphics device:

> dev.off()
httpgd 
     4 

After that dev.list() should only show a httpgd device:

> dev.list()
httpgd 
     4 

The problem should not reappear afterwards, even after resizing the pane.
