RStudio

httpgd works with RStudio:

httpgd plot viewer in RStudio
httpgd plot viewer in RStudio

Usage

Open the plot viewer in the RStudio Viewer tab:

library(httpgd)
hgd()
hgd_view()

Or open it in an external browser:

hgd_browse()

Troubleshooting

Resizing the Viewer tab while a plot exists in the Plots tab can cause RStudio to activate its own graphics device. When this happens, httpgd shows “Device inactive.” in the Viewer tab.

Check dev.list(), you will see an extra RStudioGD device:

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

Close it with dev.off():

> dev.off()
httpgd
     4

Now only the httpgd device remains. The issue should not reappear.
