i am dealing with my panle data,and i have to decided if i should use
fixed-effect model or random effect model.i know the hausman test can help.
and anyone knows if any function can do these?
thank you.

You have two asynchronous processes here: your R function will return,
leaving a Tk widget up. Duncan Murdoch's solution is to give you a
function that will retrieve at some future stage the result of the last
press (if any) of Get coordinates button. Is that what you want?
I think it is
To illustrate (?) Professor Ripley comments, I send you an example (stolen in
various places...).
Note the tkwm.resizable(tt, 0, 0) directive that prevents the window rescaling
(if not,the coordinates will not be correct).

Hi Thomas,
Your code works perfectly!
Thanks a lot,

1) can R do Random-effects GLS regression which i can get from Stata?

I want to include missing values in my barplot to get the correct x-axis,
for example,
x - c(1,2,3,4, 9)
y - c(2,4,6,8,18)
barplot(y)
The above looks wrong because the last height in y should be a long way
over.
So I want to do something like...

I see, what comes out of this longish thread is:

examples, so it is time to provide patches for both barplot() and
barplot2() (for the latter, you might want to contact the

Dear R users,
I am trying to fit a glm with a distribution free family, link = log and
variance = constant*mu. I guess I have to use the quasi family but the choices
of variance are restricted to constant or mu or mu^2..., I don't know the way
to choose the variance that I need, i.e.

Have you considered computing and plotting sample averages and
variances for different subgroups of the data then plotting variances
vs. averages? This was suggested by Fahrmeir and Tutz (2001)
