Hi Chris, Have you read the documentation for stat_smooth? It's not clear to me what the problem is, because I'm not sure what the defaults are. But since the default's are not working, I would try it with different settings. See http://had.co.nz/ggplot2/stat_smooth.html. -Ista > > > Thanks! > Chris ______________________________________________ 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.
