Hi Ross, You are indeed missing something simple. If there are 60 bars, the axis runs from 1 to 60, and you want a label at every second one, rather than at every one.
Like this (with 10 instead of 60): testdata <- matrix(runif(100), ncol=10) boxplot(testdata, xaxt="n") axis(1, at=seq(1.5, 9.5, by=2), labels=letters[1:5]) Sarah On Sun, Jun 13, 2010 at 9:40 AM, RCulloch <ross.cull...@dur.ac.uk> wrote: > > Hi R users, > > This seems like a simple problem but I have searched nabble for the answer > and can't seem to find it. > > All I want to do is produce a boxplot where I have two boxes for one > Individual but on the xaxis I only have one tick mark centred between the > boxes so I can add the Individuals' name.
