The PPM (Portable Pixel Map) format defines one of the simplest storage formats available for image data. It is basically a raw 8bit RGB stream with a few bytes of information in the start. It goes without saying, that this file format is horribly inefficient and should only be used if you want to play around with a simple file format, or need a file-based image stream.

agg_ppm(filename = "Rplot%03d.ppm", width = 480, height = 480,
units = "px", pointsize = 12, background = "white", res = 72)

## Arguments

filename The name of the file. Follows the same semantics as the file naming in [grDevices::png()], meaning that you can provide a [sprintf()] compliant string format to name multiple plots (such as the default value) The dimensions of the device The unit width and height is measured in, in either pixels ('px'), inches ('in'), millimeters ('mm'), or centimeter ('cm'). The default pointsize of the device in pt The background colour of the device The resolution of the device. This setting will govern how device dimensions given in inches, centimeters, or millimeters will be converted to pixels. Further, it will be used to scale text sizes and linewidths

## Examples

file <- tempfile(fileext = '.ppm') agg_ppm(file) plot(sin, -pi, 2*pi) dev.off()
