I ran the following script from xyplot Examples using Tin-R on
Windows and saw no plot produced.
EE <- equal.count(ethanol$E, number=9, overlap=1/4)
xyplot(NOx ~ C | EE, data=ethanol,
prepanel = function(x,y) prepanel.loess(x, y, span=1),
xlab="Compression Ratio", ylab="NOx (micrograms/J)",
panel = function(x,y) {
panel.grid()(h = -1, v=2)
panel.xyplot(x,y)
panel.loess(x,y, span=1)

aspect = "xy")
The Rgui showed
source(.trPaths[5])
Without any error msg. Did I miss anything? Please enlighten me.
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) #???
