Hi:
Here's a reproducible example:
d <- data.frame(grp = factor(rep(c('x', 'y'), each = 5)),
ev = rnorm(10), dv = rnorm(10))
labl <- list(expression(italic('x')), expression(italic('y')))
ggplot(d, aes(x = ev, y = dv, shape = grp)) + geom_point() +
scale_shape_manual('Group', breaks = levels(d$grp),
values = 1:2,
labels = labl)
HTH,
Dennis
