This works for me: ggplot(scatter_data,aes(x=x_var,y=y_var,))+ geom_point()+ geom_smooth(se=TRUE,fill="blue",color="black",linetype="dashed") + geom_ribbon(stat="smooth", aes(ymin=after_stat(ymin), ymax=after_stat(ymax)), fill=NA, color="black")+ theme_cowplot() Cheers, Berwin ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
