Hi Patrick
Not sure what you finally want to achieve but will this do?
I have reduced the size of the text to make them readible
dotplot(variety ~ yield | year+ site, barley,
strip = strip.custom(which.given = 2, style = 4,
factor.levels = paste(levels(barley$year),
substring(levels(barley$site), 1, 1)),
par.strip.text = list(cex = 0.75))
)

Suppose I wanted to plot the barley data like this:
dotplot(variety ~ yield | year+ site, barley,
strip = strip.custom(style = 4))
The factor levels are far too long for that to be useful. I can
overcome that problem if I shorten the levels like this:
dotplot(variety ~ yield | year + site, barley,
strip = strip.custom(style = 4,
factor.levels = substring(levels(barley$site), 1, 1)))
But that messes up the year levels. So I try to have it influence
only the site levels:
dotplot(variety ~ yield | year+ site, barley,
strip = strip.custom(which.given = 2, style = 4,
factor.levels = substring(levels(barley$site), 1, 1)))
But then the year strip is omitted altogether. How do I specify
a different list for different which.given numbers?
In this case, I know I could simply redefine the levels in the factor
but that's not an option where I wish to apply this method.
TIA
Patrick
