[R] Number format in log-scaled lattice xyplots

Thanks - I wasn't thinking about it the right way, and I didn't know
where to focus my investigation of the examples.

Thank you very much for pointing me at the specific example that solved
my problem.

For others who might have the same question, that would be the part of
the example that transforms the label values using 2^value, which turns
the label from something that looks like "2^3" into an actual 8.

Actually, other parts of the example are also very enlightening for
other useful things to do with tick labels.

Doesn't the first (densityplot) example in ?yscale.components.default
do this? Other relevant examples are
