how do I check whether a plot was written to file in R

If I execute the following R code, a file will be created

png('tempfile.png', width = 500, height = 500)
plot(1:10)
dev.off()

If I don't plot anything. No file is created.

png('tempfile.png', width = 500, height = 500)
#plot(1:10)
dev.off()

What is the best way to check whether the file was created at all?

You can use file.exists

file.exists("tempfile.png")

If you are modifying files you can also check when a file was last modified with file.info in the mtime column. There is also creation time ctime and last access time atime along with a few other metrics that may or may not be of interest to you.
