Hi, Stupid question I guess but I can't figure out how to have a span of 0.5 instead of 1 in my graph. Actually, I want to create a plot with x(-2,2) and y(-2,2) and an step of 0.5 along the axis. Does somebody can help me ? Is it in par(), axis() or plot() that I have to add something ?

Hi, I think the following example would help: plot(-2:2,-2:2, xaxt="n", yaxt="n") axis(1, at=seq(-2,2,by=0.5)) axis(2, at=seq(-2,2,by=0.5)) You have to specify *axt="n" in order to not draw them initially, and then draw your own axis using at=c(whatever values you want the tickmarks to be drawn).
