Hello all, I've got a scatter plot, for which I create a regression line using: reg<- lm(yvars~xvars) and can plot the regression through the scatter just fine. I'd like to add two additional lines on the scatter plot: one being regressionline+standard deviation, the other being regressionline-standard deviation, thus creating some kind of 'band' for the scatter.
Any help will be much appreciated. Thanking you in advance, George. ______________________________________________ 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.
