Dear R-Users,

How can I use chisq.test() as a goodness of fit test? Reading man-page I’ve some doubts that kind of test is available with this statement. Am I wrong?

X2=sum((O-E)^2)/E)

O=empirical frequencies
E=expected freq. calculated with the model (such as normal distribution)

See:
http://www.itl.nist.gov/div898/handbook/eda/section3/eda35f.htm for X2 used as a goodness of fit test.

Any help will be appreciated.
Thank a lot. Bye.
Vito
