Thank you very much

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
here there is an example extracted from polr help in MASS:
The function could be:
temp <- function(form, dat) {
house.plr <- polr(formula =
form, weights = Freq, data = dat)
coeff <- summary(house.plr)
return(coeff)}
Why do you try to redefine the coeff extractor function?
Try calling the results of summary summ or some
other obvious name and I think you will find the problem goes away.

Firstly, don't call your matrix 'matrix'. Would you call your dog 'dog'?
Anyway, it might clash with the function 'matrix'.
-- Barry Rowlingson
R-help (October 2004)
the function can be called by:
temp(Sat ~ Infl + Type + Cont, housing)
where all data is available from MASS, as it is
an example in R Help on 'polr'.
Results are:
Re-fitting to get Hessian
Error in eval(expr, envir, enclos) : object "dat" not found

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),
but when the above statements are enclosed in a
function, summary reports the following error:
Error in eval(expr, envir, enclos) : object "dat" not found
Someone knows how I can solve the problem?
By giving us a short reproducible example?
Specifically we do not know:
1 - what formula1 is
2 - what the structure of data1 is
3 - what the enclosing function looks like
4 - what dat is
Thanks for any help.

[R] summary polr
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), but when the above statements are enclosed in a function, summary reports the following error: Error in eval(expr, envir, enclos) : object "dat" not found Someone knows how I can solve the problem?
