slurm - Save a plot in R without png dev.off()

Question

I am running an R script in a batch mode on my university Linux HPC cluster. I am using a module with pre-installed R packages, so I don't think I can install anything. R version is 4.0.3

I am trying to save the plots with

png("filename.png")
plot()
dev.off

But I got a "unable to start device png" error with "unable to open connection to X11 display ''" warning

I found some similar problems here, but neither of the suggested solutions worked. I tried

options(bitmapType='cairo')
png("plot.png", res=250, height=40, width=80)
plot()
dev.off()

and

png("plot.png", type='cairo', res=250, height=40, width=80)
plot()
dev.off()

still have the same error

Are there other ways to save a plot without using png() and dev.off()?

UPD: I checked capabilities() and both png and jpeg are FALSE there. Is there any way I can at least look at those plots? I do not have to save them
