Dear Christian, >From the Rcmdr menus, select "Statistics -> Summaries -> Frequency distributions", and check the "Chisquare goodness of fit test" box in the resulting dialog. This will bring up a dialog box where you can enter hypothesized probabilities from which expected frequencies will be calculated.
