I would like to substitute this labels by math expression. I used the following codeCase<-factor(rep(1:2,each=300)) levels(Case) <- c(expression(R^2),expression(sigma_[i])) xx<-rnorm(600,0,1) yy<-rnorm(600,0,1) xyplot(yy~xx|Case) But the label did not change to mathematical expressions. Any ideas?You should be looking at the strip.custom function. It has worked examples.
The worked examples only illustrate a few of the arguments. The factor.levels argument is probably what you wanted:
xyplot(yy~xx|Case,strip=strip.custom(factor.levels= c( expression(R^2), expression(sigma_[i]) )
)
