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

In eddelbuettel/lwplot: An Lighter-Weight Implementation of Leland Wilkinson's Grammar of Graphics

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 (function or any of the recognized extensions, e.g. "pdf"). By default, extracted from filename extension. ggsave currently recognises eps/ps, tex (pictex), pdf, jpeg, tiff, png, bmp, svg and wmf (windows only).
path	Path to save plot to (combined with filename).
scale	Multiplicative scaling factor.
width, height	Plot dimensions, defaults to size of current graphics device.
units	Units for width and height when specified explicitly (in, cm, or mm)
dpi	Resolution used for raster outputs.
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

## 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)
