dear all, I have a very simple question but I could not figure out.
I need to make plots with grid in the background. something like I old retrive like this a=runif(100)*10 b=runif(100)*10 plot(a,b, pch=20, xlim=c(0, round(max(a))), ylim=c(0, round(max(b)))) vs=seq(0, max(a), 0.5) for(i in 1:length(vs)){ abline(v=vs[i], col="lightgrey") } hs=seq(0, max(b), 0.5) for(i in 1:length(hs)){ abline(h=hs[i], col="lightgrey") } points(a, b, pch=20) as you can see it is not very convenient -- john [[alternative HTML version deleted]] ______________________________________________ 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.
