ggsave: partial argument match of 'file' to 'filename' #2355

I have all the warnPartialMatch* options set to TRUE in my .Rprofile. Every time I use ggsave() I get this warning. I took at look at plot_dev() and couldn't quickly determine if file (vs filename) is necessary for some devices? But for png() at least, it would be nice if this line was dev(filename = filename, width = dim[1], height = dim[2], ...).


options(warnPartialMatchArgs = TRUE)

p <- ggplot(iris, aes(x = Petal.Length, y = Sepal.Width)) + geom_point()

ggsave("iris.png", p)
#> Saving 7 x 5 in image
#> Warning in grDevices::png(..., res = dpi, units = "in"): partial argument
#> match of 'file' to 'filename'

This has been bugging me too. It is weird that some devices take file but others take filename.

This still seems to be around.
