[R] change y axis distance
Hi I got a barplot that has values between 0-150 and the y-axis shows the steps 0 50 100 and 150 but I would like to change it to 0 10 20 30... ...130 140 150 Dont really know the word in english so sry about it beeing abit confusing :) Thx for your help Joel -- View this message in context: http://r.789695.n4.nabble.com/change-y-axis-distance-tp2548363p2548363.html Sent from the R help mailing list archive at Nabble.com. __ 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.

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.

You can probably get the fifteen labels by adding: # set the axis labels to all horizontal text par(las=1) # add the yaxt argument to plot plot(...,yaxt=n,...) # display the axis axis(2,at=seq(0,150,by=10),labels=seq(0,150,by=10)) If some of the labels are missing, you might have to turn to staxlab in the plotrix package or a similar function.
