ggplot2 (version 2.2.1)

ggsave: Save a ggplot (or other grid object) with sensible defaults

Description

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. Applies only to raster output types.
limitsize
When TRUE (the default), ggsave will 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

Run this code
## 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)
# ## End(Not run)
