Dear Spencer,
In addition to the approaches already suggested, there is the recode()
function in the car package.
Or this way:
levels(ftpain) <- list(
none="none",
intermediate=c("mild", "medium"),
severe="severe")
Or this (not quite as general):
levels(ftpain) <- c("none", "intermediate", "intermediate", "severe")
