WebSecond, use plot () instead of plot.Predict to save work. Third you can easily generate plots for both sexes, e.g. using Predict (fit, age, sex, fun=exp) # exp=anti-log; then plot (result) or plot (result, ~ age sex). You don't use "x=NA" in Predict. rms uses lattice graphics so usual par graphics parameters and mfrow don't apply.
