Thank you Pascal but unfortunelately i still didn't figure out how to change the numbers presented at the y-axis.
I looked up your suggestions but if I'm right, yaxt can set if the axis is presented (yaxt="s") or suppressed (yaxt="n") which does not help for changing the values on the y-axis. The 'at' argument did solve my problem but in a clumsy way. Although I'm happy that I managed, does anyone know how to do the same job in a more convenient way? This is the 'clumsy' code I used: boxplot((fitted(finalfit4) *100) ~ instabilitydata2$MRI_Diag_Instab_rev, ylim=c(0,100), xlab="MRA diagnosis", ylab="Predicted probability (%)") axis(side=2, at="10") axis(side=2, at="30") axis(side=2, at="50") axis(side=2, at="70") axis(side=2, at="90") Kind regards, Tobias -----Oorspronkelijk bericht----- Van: Pascal Oettli [mailto:kri...@ymail.com] Verzonden: vrijdag 29 maart 2013 8:44 Aan: Berg, Tobias van den CC: 'r-help@r-project.org' Onderwerp: Re: [R] changing y-axis intervals in a boxplot Hello, ?par (particularly the 'yaxt' argument) ?axis ('side' and 'at' arguments) Hope this help, Pascal On 29/03/13 16:37, Berg, Tobias van den wrote: > Dear R-users, > > I'm a bit of a rooky in R and do not know how to change the y-axis intervals > of a boxplot. > > The y-axis in my boxplot ranges from 0 to 100 which is fine.
