'ggplot2 png file without background
Since a few months, ggplot2 started to save png files with a transparent background. The code output in Rstudio and when saved as pdf looks great. It happens mainly with the use of themes when I omit the gray panel background. I tested it on my macbook with "Preview" and on a Windows Computer with the "foto viewer" there.
library(ggplot2)
library(dplyr)
mtcars %>%
ggplot(aes(x = mpg, y = cyl)) +
geom_point() +
theme_minimal()
This is how the file should look (with a white background):
ggsave("test.png", dpi = 300)
#> Saving 7 x 5 in image
ggsave("test.pdf")
#> Saving 5.54 x 4.56 in image

This is how the files look side-by-side:
I have tested all graphic devices in the "backend" tab under prefences/general/graphics and I also tested everything in R (not R Studio) with the same result.
Solution 1:[1]
set the bg argument to "white", e.g.
ggsave("test.png", dpi = 300, bg = "white")
This argument will be passed to grDevices::png via the ... argument. bg controls the background of the device.
