I was wondering what would be the best way to put a vertical line on a graph made with plot(). I can get an horizontal line by plotting a vector where every element has the same value but it is not as clear how a vertical line should be done.
Thanks very much, Peter. ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
