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
