[R] How to draw plot marks without label?

[Paul Murrell]

Hi

Do you mean like this ... ?


stripchart(df$Y ~ df$X,
            method = "jitter", offset=1/3,
            vertical = TRUE, las=1,
            pch=16, cex=2,
            ylab="Y", xlab="X",
            main="Example",
            axes=FALSE)
box()
axis(1)
axis(2, labels=FALSE)
axis(4, labels=FALSE)
