Fortify methods for objects produced by multcomp

Usage

# S3 method for glht
fortify(model, data, ...)

# S3 method for confint.glht
fortify(model, data, ...)

# S3 method for summary.glht
fortify(model, data, ...)

# S3 method for cld
fortify(model, data, ...)

Arguments

model: an object of class glht, confint.glht, summary.glht or multcomp::cld()
data, ...: other arguments to the generic ignored in this method.

Examples

if (require("multcomp")) {
amod <- aov(breaks ~ wool + tension, data = warpbreaks)
wht <- glht(amod, linfct = mcp(tension = "Tukey"))

fortify(wht)
ggplot(wht, aes(lhs, estimate)) + geom_point()

CI <- confint(wht)
fortify(CI)
ggplot(CI, aes(lhs, estimate, ymin = lwr, ymax = upr)) +
   geom_pointrange()

fortify(summary(wht))
ggplot(mapping = aes(lhs, estimate)) +
   geom_linerange(aes(ymin = lwr, ymax = upr), data = CI) +
   geom_point(aes(size = p), data = summary(wht)) +
   scale_size(transform = "reverse")

cld <- cld(wht)
fortify(cld)
