In bstaton1/StatonMisc: Common Functions Used in B. Staton's Code

Description

General purpose graphics devices saved to files, where the file type is determined by the file name

Usage

file_device(filename, width = 5, height = 5, res = 600, ...)

Arguments

filename	the name of the output file. Can be a path but must contain a file extension at the end (e.g., "path/to/dir/file.png")
width	the width of the device, in inches. Defaults to 5
height	the height of the device, in inches. Defaults to 5
res	the resolution of the device, in pixels per inch. Defaults to 600. Has no effect if the extension is ".pdf" or ".eps"
...	optional arguments passed to the graphics device generating function (e.g., png)

Details

Accepted file extensions include:

• ".pdf" (calls pdf)

• ".png" (calls png)

• ".bmp" (calls bmp)

• ".jpg" (or ".jpeg", both call jpeg))

• ".tif" (or ".tiff", both call tiff))

• ".eps" (calls cairo_ps)

Note

A call to dev.off is still required after the plotting code (see examples).

Examples

## Not run: 
# use a png device
file_device("test.png")
hist(rnorm(1000), col = "grey")
dev.off()

# use a pdf device: can dump multiple plots in one file!
file_device("test.pdf")
hist(rnorm(1000), col = "grey")
boxplot(rnorm(1000), col = "grey")
dev.off()

## End(Not run)
