ggsave
Save a ggplot (or other grid object) with sensible defaults
ggsave() is a convenient function for saving a plot. It defaults to
saving the last plot that you displayed, using the size of the current
graphics device. It also guesses the type of graphics device from the
extension.
Usage
ggsave(filename, plot = last_plot(), device = NULL, path = NULL,
scale = 1, width = NA, height = NA, units = c("in", "cm", "mm"),
dpi = 300, limitsize = TRUE, ...)Arguments
- filename
File name to create on disk.
- plot
Plot to save, defaults to last plot displayed.
- device
Device to use. Can be either be a device function (e.g.
png()), or one of "eps", "ps", "tex" (pictex), "pdf", "jpeg", "tiff", "png", "bmp", "svg" or "wmf" (windows only).- path
Path to save plot to (combined with filename).
- scale
Multiplicative scaling factor.
- width, height, units
Plot size in
units("in", "cm", or "mm"). If not supplied, uses the size of current graphics device.- dpi
Plot resolution. Also accepts a string input: "retina" (320), "print" (300), or "screen" (72). Applies only to raster output types.
- limitsize
When
TRUE(the default),ggsavewill not save images larger than 50x50 inches, to prevent the common error of specifying dimensions in pixels.- ...
Other arguments passed on to graphics
device.
Examples
# NOT RUN {
ggplot(mtcars, aes(mpg, wt)) + geom_point()
ggsave("mtcars.pdf")
ggsave("mtcars.png")
ggsave("mtcars.pdf", width = 4, height = 4)
ggsave("mtcars.pdf", width = 20, height = 20, units = "cm")
unlink("mtcars.pdf")
unlink("mtcars.png")
# specify device when saving to a file with unknown extension
# (for example a server supplied temporary file)
file <- tempfile()
ggsave(file, device = "pdf")
unlink(file)
# }
