l_export {loon} | R Documentation |
Export a loon plot as an image
Description
The supported image formats depend on your system and Tcl/Tk configuration. Export to PostScript ('.ps', '.eps') always works. Export to PDF ('.pdf') works if the command-line tool 'epstopdf' is installed. Export to bitmap formats such as '.png', '.jpg', '.bmp', '.tiff', or '.gif' may work if supported by your Tcl/Tk environment — this often, but not always, requires the Img Tcl extension.
If a selected format fails, use '.ps' or consider capturing a screenshot.
