If you want to draw the ticks at specific locations rather than the ones R chooses for you, turn off the axes in your plot call and then cook your own axis using the axis() function. Here's an example using dummy data: set.seed(123) mdat <- rpois(10, 10) names(mdat) <- LETTERS[1:10] barplot(mdat, axes = FALSE) ## label at 1, 2, 3 etc not 2, 4, 6, etc axis(side = 2, at = seq(1, max(mdat), by = 2)) For you specific axis call, try: axis(side = 2, at = seq(0, 150, by = 10)) HTH G -- %~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~% Dr. Gavin Simpson [t] +44 (0)20 7679 0522 ECRC, UCL Geography, [f] +44 (0)20 7679 0565 Pearson Building, [e] gavin.simpsonATNOSPAMucl.ac.uk Gower Street, London [w] http://www.ucl.ac.uk/~ucfagls/ UK.
