I am not aware of an R-package but there are several applications that produce tables from graphs which you can import into R afterwards. A few examples: g3data (LINUX, opensource) engauge (LINUX/Windows, opensource) Grab it! (Windows, commercial) Datathief (LINUX/Windows/Mac, shareware) UN-SCAN-IT (Windows/Mac, commercial) Google digs up quite a few additional hits with "digitizing graph data". cu Philipp -- Dr. Philipp Pagel Lehrstuhl für Genomorientierte Bioinformatik Technische Universität München Wissenschaftszentrum Weihenstephan 85350 Freising, Germany http://mips.gsf.de/staff/pagel ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
