I would like to set the 'xlab' on the 'upper' x axis. The following code shows roughly what I want by way of (one possible) expected behaviour.
par(mar=c(5.1, 4.1, 5.1, 2.1)) plot(rnorm(10), rnorm(10), xlab="the lower one") axis(3, xlab="the upper one????") There are various other ways that could be expected to work, but hopefully the above is clear enough to show you what I want to achieve. The following works, but is fragile (works without resizing the window of an X11 device). title(xlab="the upper one", line=-28) Is there any better way to do it other than tinkering with 'line='? Here is the same code as above but with comments just for reference. # Give upper and lower margins an equal size par(mar=c(5.1, 4.1, 5.1, 2.1)) # Plot (labeling the lower x axis) plot(rnorm(10), rnorm(10), xlab="the lower one") # Add the upper x axis (labeling fails!) axis(3, xlab="the upper one????") # Works but is fragile title(xlab="the upper one", line=-28) [[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.
