Displaying ggplot2 figures via RCall? 

Hi, I am wondering how do I make a figure done in ggplot2 via RCall show up in Pluto? At the top of a cell when I run it, I just see RObject{VecSxp} but the figure itself does not render as it would in a Jupyter Notebook. Do you have to use a Julia plotting package in order for things to show up in the notebook?

Thanks
