Hi, I am trying to run a very simple Quarto document, cell by cell, using the visual editor. Something is going wrong with how R saves its plots that prevents me from running additonal cells.
I created an Rproject in a folder on my hard drive (running MacOS Sonoma 14.6.1). Within that project, I created a Quarto document and saved it. I load ggplot2 and create a plot successfully.
{r}
library(ggplot2)
ggplot(cars, aes(x =speed, y=dist )) + geom_point()
If I make a mistake, say, ggplot(cars, aes(x =speed, y=mistake )) + geom_point() I get this error, as expected:
Error in `geom_point()`:
! Problem while computing aesthetics.
ℹ Error occurred in the 1st layer.
[...more messages...]
16. rlang (local) FUN(X[[i]], ...)
If I fix the error, or move on to a new cell, all is well. However, after a few minutes, with the exact same code (and same mistake), the console will return this message appended to the normal error message:
Error in dev.off() :
QuartzBitmap_Output - unable to open file '/Users/mds/test_quarto/.Rproj.user/shared/notebooks/18E8589E-test3/1/CB1B30DC218300bf/cidwre0mi6mw6_t/_rs_chunk_plot_001.png'
Once this appears, R is dead in the water. Any other cell I try to run will display the "busy" clock, and I can't run anything until I restart R (though I can still render the PDF, strangely).
I cannot seem to reproduce this error simply by running the exact same code—it seems to be depend on how much time has passed since I last restarted R. I'm guessing, therefore, it has something do with Rstudio talking to my hard drive. At first I though it was a Dropbox sync issue but creating a new project outside of Dropbox in the root directory has not helped.
What's going on and what can I do about it? I'm running the latest release of RStudio and R. This has been going on for several months.
