That's not what Sebastian requires.

He would like the axis tick marks to be drawn, but without values at the tickmark locations, as opposed to the axis labels.

There is not a direct way, but a possible workaround:

 plot(rnorm(20), col.axis = "white")

This sets the tick mark label color to be the same as the background, thus unseen.

If you have an alternate background color, adjust the above accordingly.

For plot.default() specifically and functions that behave similarly internally with respect to the axes, you could use:

  plot(rnorm(20), labels = FALSE)

where the labels argument is passed to the internal axis drawing function. However, since 'labels' is passed as a "..." argument, you end up with a warning about 'labels' not being able to be set in a high level plot function, since it gets passed as a graphical par.

Ultimately however, I do think that this behavior is best controlled by using "axes = FALSE" and then calling axis(x, labels = FALSE):

 plot(rnorm(20), axes = FALSE)
 axis(1, labels = FALSE)
 axis(2, labels = FALSE)


Non-standard plot behavior is best done outside of the default plot function, where you have maximum flexibility.
