[R] How to set the scale of axis?

[Gabor Grothendieck]

Try this:

plot(1:100, xaxt = "n")
axis(1, c(1, 20, 40, 60, 80, 100))

# and optionally add this third line
axis(1, 1:100, FALSE, tcl = -0.3)

See ?par (for the xaxt argument to plot) and ?axis .  ?plot and
?plot.default have info on the plot command.  A good source of
sample code for graphics is:
