Well, you might try ?xyplot -- in particular the "scales" list section and in particular there the "tck" parameter. Adding tck = c(1, 0) to the "scales =" list will probably solve your problem.
Bert, I missed the end of the tck description in the book (the same text as the help file but with more information) where it mentions that tck can be a vector of length 2 where the first element affects the left/bottom axes and the second element affects the right/top axes. I also did not grok turning the first element on and the second element off. Now I wonder why this wasn't an issue before now in the xyplots I created.
