Have you considered using the lattice-style panel functions that hexbin provides:
mixdata <- data.frame(x = c(rnorm(5000),rnorm(5000,4,1.5)), y = c(rnorm(5000),rnorm(5000,2,3)), a = gl(2, 5000)) hexbinplot(y ~ x, mixdata, aspect = 1, panel=function(x, y, ...){ panel.hexbinplot(x,y,...) panel.abline(v=c(-1,0,1), h=c(-1,0,1), col='red', lwd=3) }, trans = sqrt, inv = function(x) x^2) On Sat, Jan 3, 2009 at 12:43 PM, Rodrigo Fernandes Ramalho <rof...@ig.com.br> wrote: > Hello, > > I would like some help to plot a vertical line on a scatterplot build with > hexbin package. > > I just need to plot a vertical line on the graph to mark a threshold value > on x axis. > > It would be better if the parameter of the plot line function respect > the x axis scale. > > Thanks, > > Rodrigo > > [[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. > -- Jim Holtman Cincinnati, OH +1 513 646 9390 What is the problem that you are trying to solve? ______________________________________________ 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.
