To help you to begin to do a code that we could enhance, here are some
functions that will be usefull for you:
> qchisq(p=1-0.05, df=1)
[1] 3.841459
Then, using a range of df, from example 1 to 10:
> qchisq(p=1-0.05, df=1:10)
[1] 3.841459 5.991465 7.814728 9.487729 11.070498 12.591587
14.067140 15.507313 16.918978 18.307038
To help to present a nice table:
> X <- qchisq(p=1-0.05, df=1)
> format(X, digits = 4+log10(X), width = 10)
[1] " 3.841"
Or use the xtable package
Sincerely
Marc
