I have suspect that the most common answer to this will be 'don't', for all the reasons statisticians don't like mixing vertical scales on the same plot. See http://www.perceptualedge.com/articles/visual_business_intelligence/dual-scaled_axes.pdf for one article on that topic.
But if you must, is there any reason you can't divide the first row by (say) 1000, barplot normally with axes=false, and then put an explicit axis up each side with something like axis(2, at=seq(0,3, 0.5), labels= seq(0,2500,500)) ) #first row axis, left column axis(4) S Ellison > -----Original Message----- > From: R-help [mailto:r-help-boun...@r-project.org] On Behalf Of Adrian > Johnson > Sent: 12 October 2016 17:21 > To: r-help > Subject: [R] barplot beside=TRUE - values differ on scales > > Dear group, > I have been struggling to barplot two different measurements from one > subject.
