Hi,I have a result from polr which I fit a univariate variable (of ordinal
data) with probit function. What I would like to do is to overlay the plot of
my fitted values with the different intercept for each level in my ordinal
data. I can do something like:lines(rep(intercept1, 1000),
abline(v=c(intercept1,intercept2,intercept3))
