TL;DR: There’s a colour picker addin in shinyjs and a ggplot2 marginal plots addin in ggExtra.
Any R user who hasn’t been spending the past 2 months under a rock should know by now about RStudio’s new exciting features: addins and gadgets.

You can either run the colour picker as an addin or as a gadget. To access it as an addin, click on the RStudio Addins menu and select Colour Picker. To access the colour picker gadget, run the colourPicker() function. When running the gadget, you can …read more
