grobsave: Save a ggplot with sensible defaults

In johnDorian/ggsnippets: A few addons for the ggplot2 package

Description

ggsave is a convenient function for saving a plot. It defaults to saving the last plot that you displayed, and for a default size uses the size of the current graphics device. It also guesses the type of graphics device from the extension. This means the only argument you need to supply is the filename.

Usage

grobsave(filename = default_name(plot), plot = NULL,
  device = default_device(filename), path = NULL, scale = 1,
  width = par("din")[1], height = par("din")[2], units = c("in", "cm",
  "mm"), dpi = 300, limitsize = TRUE, ...)

Arguments

filename	file name/filename of plot
plot	plot to save. This needs to be specified, otherwise the function will fail.
device	device to use, automatically extract from file name extension
path	path to save plot to (if you just want to set path and not filename)
scale	scaling factor
width	width (defaults to the width of current plotting window)
height	height (defaults to the height of current plotting window)
units	units for width and height when either one is explicitly specified (in, cm, or mm)
dpi	dpi to use for raster graphics
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 to graphics device

Details

grobsave currently recognises the extensions eps/ps, tex (pictex), pdf, jpeg, tiff, png, bmp, svg and wmf (windows only).

Examples

## Not run: 
ratings <- qplot(rating, data=movies, geom="histogram")

ggsave("length-hist.pdf")
ggsave("length-hist.png")
ggsave("ratings.pdf", ratings)
ggsave("ratings.pdf", ratings, width=4, height=4)
# make twice as big as on screen
ggsave("ratings.pdf", ratings, scale=2)
