Sorry to bother you again, But I have two other questions :
1. How do I change symbols (dots) for each group? I tried : For group 1, n=5. points(x=groups[1:5],y=data[1:5],type=pch). The issue is that it doesn't select the right points, or coordinates. 2. How can I increase horizontal spacing between dots from the same group which are at the same vertical level? I have some overlapping values for replicates. I tried to modify "intervals" and "offset" but it doesn't work. Thanks again. -- View this message in context: http://r.789695.n4.nabble.com/Produce-a-prism-like-plot-tp4648844p4648870.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.
