Lattice xyplot multipanels

Sorry about the word "brackets".. Yes, I meant curly  braces! I have not heard of "curley braces"! :).  Curly braces surrounding the values of "strip.levels" appear on the strip of multipanel plots.

Thanks,
Santosh

Dear Rxperts,
I have a strange situation.. I see curly brackets

Wait right here. What do you mean by "brackets"? In some locales, such as mine,  that might mean "[" ; in other domains... well,  who knows? I don't see any "[".

The Urban Legends Newsgroup used to have a saying: TWIAVBP,  which is an initialism for: The World Is A Very Big Place. Pleas realize that language is local.

around "strip.levels" in
multipanel strips while using lattice::xyplot. .How do I get rid of the
curly brackets?

Curly "brackets"? You mean curley braces? I see some of them in the code, but why in the world would one want to remove valid curley-braces in code? They just function as delimiters.

For some reason, I am not able to reproduce the problem
using an example below...

What problem?  .. are you unable to reproduce? The code runs without error on my machine.

Any suggestions are highly welcome!
Thanks,
