Hi
here there is an example extracted from polr help in MASS:
The function could be:
temp - function(form, dat) {
house.plr - polr(formula =
form,
That's not it (the function is 'coef' not 'coeff', and R can tell
functions and lists apart).
If you read the help page for polr you will see you could have used
Hess=TRUE. It works then. THAT is why we needed an example, to see how
you used the function.

Hi all,
I have a problem to estimate Std. Error and t-value by “polr” in library Mass.
They result from the summary of a polr object.
I can obtain them working in the R environment with the following statements:
temp - polr(formula = formula1, data = data1)
coeff - summary(temp),
