# [R] axis() plot() - step

```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).

Cheers,

Ott
