I recommend the "effects" package.

Package: effects
Version: 3.0-0
Date:    2014/03/20
Title:   Effect Displays for Linear, Generalized Linear,
         Multinomial-Logit, Proportional-Odds Logit Models and
         Mixed-Effects Models


plot(Effect(c("gre"), cfelr, grid = TRUE))

Or, for interactions, eg:

plot(Effect(c("gre", "rank"), cfelr, grid = TRUE))
