R help - Oct 2007 - How to plot with txt or symbol instead of number as x-axis scale ?

Dear R-list

My question is exactly as the subject, I did search the archieve but
failed to find relevant message, in more details:

The simplest example, 4 factors and 4 value like below:
10    20      30     40
A       B        C      D

if I plot the value, the x-axis will be scaled as 1,2,3,4 with each
represent a level. How can I change the x-axis scale to A,B,C,D ?

Regards
young

There are probably much more fancy ways to do this, but since no one
else has posted a response, here's what I would do:
> plot(seq(10, 40, 10), axes = FALSE)
> axis(1, at = 1:4, lab = LETTERS[1:4])
> axis(side = 2)
> box()
