Hi folks Run; > ToothGrowth > attach(ToothGrowth) > toothgrowth=lm(len~dose)
adding abline: > abline(toothgrowth) I got it done adding single abline. How to add more ablines on the same diagram? I found following thread, applying "mapply" command; Plotting multiple ablines http://www.mail-archive.com/r-help@r-project.org/msg51543.html mapply(abline, (converge$kY + tan((90-converge$kT) * pi / 180)*(-converge$kX)), tan((90-converge$kT) * pi / 180)) But couldn't resolve it. Substituting "converge" with toothgrowth" didn't work? I also look at ?mapply. Pls help. I don't have parameter of other ablines to be added. This is only a learning example. Any data can fit to them. TIA B.R.
