[R] comma as decimal separator in plots

You could try something with axis() and chartr(), like ...

    par(mfrow=c(2,1))
    plot(1:10/11, rep(1, 10), main="Standard X-Axis")    
    plot(1:10/11, rep(1, 10), main="Customised X-Axis", axes=F)
    axis(1, at=pretty(1:10/11), 
        labels=chartr(".", ",", as.character(pretty(1:10/11))))
    axis(2)
    box()

Hope that helps

Paul
