Hello,
I need to add superscripts of the strip labels of a xyplot.
For example:
xyplot(a~b|c)
Where c has 3 factor levels: A^2, A^3 and A^4. How can I introduce
expressions in the strip labels?
David has given you the answer. I'll just add that you might
want to widen the strips a bit if you use superscripted factor levels:
xyplot(Sepal.Length ~ Sepal.Width | Species, data = iris,
strip = strip.custom(factor.levels = expression(
'A'^2,'A'^3,'A'^4)),
par.settings = list(layout.heights = list(strip = 1.5)))

Here is an example that comes up on a search with terms expression&
strip.default (which I thought was the correct argument to the strip
parameter but turns out I was not remembering my documentation
correctly:
