Thanks Jim, The next issue is how i get the RP lines to cut the axes. The lines either cut the x axis at D=35 or the y axis at H=4.5.
How do I set the axes so that the lines start and end on the axes? http://r.789695.n4.nabble.com/file/n3037496/plot.jpeg -- View this message in context: http://r.789695.n4.nabble.com/Plot-Axes-tp3036571p3037496.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.
