Hi All, I am trying to build a set of plots, and build a common legend to all of them. Because I want to use a multi-line, multi-column legend layout, I cannot use the common ggplot2 legends (if I can, please tell me how). So, I would like to know how can I access the properties of a legend, so that I can extract the colours/symbols/patterns and the corresponding labels, so that I can then build my own legend. I tried using gglegend, but I cannot find out how to access its properties.
Thanks, Pedro -- View this message in context: http://www.nabble.com/ggplot2---accessing-legend-data-tp19575314p19575314.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
