While pixmap could be used, you would need to do a lot to register the image and grab the axis scales. The last time I used g3data for this, it delivered, and took care of all the registering: http://www.acclab.helsinki.fi/~frantz/software/g3data.php The current version does not seem to be available for Windows (version 1.1.4 is), is gtk+ based, there are RPMs. Roger > > ______________________________________________ > [EMAIL PROTECTED] mailing list > https://www.stat.math.ethz.ch/mailman/listinfo/r-help > -- Roger Bivand Economic Geography Section, Department of Economics, Norwegian School of Economics and Business Administration, Breiviksveien 40, N-5045 Bergen, Norway. voice: +47 55 95 93 55; fax +47 55 95 93 93 e-mail: [EMAIL PROTECTED] ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
