I am running R 4.0.3 within RStudio on my laptop with Ubuntu 20.04. I tried to use the ggpairs() function out of the GGally library and some parts of the plot can't be displayed. The value of the correlation shows strange artefacts instead of values (see picture).

I tried this with the same R version and RStudio on different operating systems (Windows 10, popOS 20.04, Linux mint 20) with no problems, so I think this must have something to do with Ubuntu 20.04. Hopefully someone faced something similar and can provide some help. enter image description here

  • For some reason it's not using a font which contains any ASCII characters. Those are the missing character symbols for the text "Corr:0.807***". So it's a font configuration or installation issue somewhere. – Martin Thornton Dec 29 '20 at 17:41
