ggarrange generates an extra figure in rpy2 magic cell of a python Jupyter notebook

[xiaohk]

I am using rpy2 to embed ggplot plots in my Python Jupyter notebook. I am also using the function ggarrange() from ggpubr to concatenate multiple plots.

If I add the argument common.legend in ggarrange(), this R magic cell will display two images (one empty image and one output figure). The cell only displays one figure if common.legend is not included.

Here is a demo of this error.

Similar discussions have been posted on stackoerflow here and here.

It should be possible to fix the problem by opening a null pdf device.

p <- ggboxplot(ToothGrowth, "dose", "len", color = "supp") 
pdf(NULL)
res <- ggarrange(p,p)
x <- dev.off()
res

Let me know if this solution works on your computer
