Dear R-community, using R.2.9.1, how do you put reference lines or grids into the _background_ of a plot? For example:
barplot(3:1) abline(h = seq(0.5, 2.5 ,0.5), col = "red", lty = "dashed") -> The lines are before the bars (and the line parts going through the bars might be considered as "chart junk", I suppose). Now, in this toy example I could just do the plot again to get the desired result: barplot(3:1, add = TRUE) But is that really in general the "natural" way to do this? Maybe I am just missing some graphical parameter that I could change (though I was not able to find one)... Thanks, Heinrich. ______________________________________________ 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.
