I got the example to work fine but had no plotting with your version  
and cannot see the difference in the code. I assigned them to t1 nd t2  
and ...
 > all.equal(t1, t2)
[1] "Component 5: target, current do not match when deparsed"
[2] "Component 29: target, current do not match when deparsed"

Looking at str applied to both does not illuminate me. I have seen  
problems on my Mac with examples copied from the help page and I  
suspect there is some invisible character sitting in a copy-pasted  
version that out mail-clients are not displaying. What happens if you  
try:

examples(xyplot)  #???
