[R] axis tick colors: only one value allowed?

[Carl Witthoft]

That only puts different colors on different axes.  I was wondering 
about the (silly) possibility of having a range of colors for the ticks 
on a given axis.

See `?axis' or try this:

     plot(0:1,0:1, type = "n", axes = FALSE)     box()
     axis(side=1, lwd.ticks = 2, col.ticks="blue")     axis(side=2, 
lwd.ticks = 2, col.ticks="red")
