Hi,
Thanks for developing and providing this resource.

I am learing how to use it, and following the examples provided on this page.

FYI, Code in section "Label Map" does not work on my machine: the map is shown, with white labels, but the evaluation continues and eventually aborts with the error message

Error in getNamespace("grDevices") : 
  Shadow graphics device error: r error 4 (R code execution error)

I use R version 4.0.4 (2021-02-15) on Rstudio Version 1.4.1717.

Hi,
I'm unable to reproduce this at the moment.
Does it work outside RStudio, using just R?
Can you provide your full sessionInfo() output?

flodebarre commented

I just tried, it is working in R outside of Rstudio. Maybe a memory issue?

I'm not sure.
It may have something to do with the graphic device backend of RStudio:

You can try to modify this and see if it works.
The next steps would be

  • re-install RStudio
  • to update all R packages (if needed).
  • to update R itself (to the next minor version, hence reinstalling all packages...)

Hi,
Has mf_label() finally worked on your machine with RStudio?

flodebarre commented

Yes, thanks for asking! The issue was with RStudio
