Why does ggplot2 work in R version 3.6.1 but not in R version 3.6.3 on the server?

Question

Currently I am working on the R Studio Pro server from my university. I am trying to plot the following using the library ggplot2:

 starttijdstipvanladenvergelijken %>%
  ggplot(aes(x=StartConnectionHour, y = perc)) +
   geom_line() +
   geom_point()

But unfortunately, I get this error:

Error in RStudioGD() : Shadow graphics device error: r error 4 (R code execution error) In addition: Warning message: In grDevices:::png("/tmp/Rtmpn4W7ks/5fd6f31151e54efab921f12ea1e3591b.png", : unable to open connection to X11 display ''

PS: When I switch from R version 3.6.3 to 3.6.1, I don't get an error, only when I am trying to plot the graph in R version 3.6.3

Answer 1

This message indicates you do not have write access to folder /tmp/Rtmpn4W7ks/

Possibly because the folder does not exist (can you create this folder?)

or because you are not the owner, or another file system permissions issue.
