suppressing non-integer labels for plot x-axis

Dear R-helpers, I am having difficulty making R plot only integer labels on the x-axis of a simple graph. I want to plot the median values of a score on each of three occasions. Non-integer occasions are impossible. But, R keeps labelling the x-axis with half-occasions, despite my attempts to stop this using the "xaxs" and "xaxp" parameters of 'plot'. p1=c(1,2,3); p2=c(5,15,25) plot(p1,p2,xlab='Occasion', ylab='Score', xlim=c(1,3), ylim=c(0,30), xaxp=c(1,3,3), xaxs='r') Could someone let me know how to suppress the non-integer labels?
In this case supress the drawing of the x-axis and specify it explicitly, see ?axis: plot(p1, p2, xlab='Occasion', ylab='Score', xlim=c(1,3), ylim=c(0,30), xaxt="n") axis(1, at=1:3) Uwe Ligges
