axis in a normal plot

Hi r-help-bounces at r-project.org napsal dne 26.09.2008 10:49:40:
Hi I have a small problem, I'm new in using R, so I hope you can help me... I'm running a logistic regression model and want to do a nice plot. The plot I have made is done a plot with the command jitter: plot(jitter(overto$age[overto$sex=="F"]),jitter(overto$neg.pos[overto $sex=="F"]),xlab="age",ylab="neg and pos") my responsvariable is positive and negative (1 and 0) and my explanatory
variable are age, year and sex. When I run my command plot the yaxis "decide" to make the axis with the numbers: -0.2, 0.2, 0.6 and 1. What command can I use to change the axis so only 0 and 1 appear?
Like in plot(rnorm(10), axes=F) axis(2, at = c(0,1)) box() Regards Petr
I have tried ylim=c(0:1) that did not work, and I tried yrange Thanks Silje ?`?.??.???`?.??.???`?.? ><(((?> Silje-Kristin Jensen Norsk Polarinstitutt / Norwegian Polar Insitute Polarmilj?senteret N-9296 Troms?

You need two steps. in your plot() set yaxt="n" so that R doesn't draw any y axis. Then, after plotting, you draw a custom y axis with axis() x <- seq.int(0,1,0.2) y <- x plot(x,y, yaxt="n") axis(2,at=c(0.2,0.6,1)) m.
