I for one think it would be much better if we could enable R to run such tests too. There are not many tests that can be done with having only the descriptive statistics. Maybe unpaired t-tests and one-way and two-way ANOVAs, chi-square, or tests I am not aware of their ability to be computed without having the raw data.

But that still can be quite beneficial when we are dealing with another study where we don't have the raw data but need to calculate the P value, or need to assess the correctness of the tests used (as a reviewer) in that study. And we don't want to calculate it manually.

Thus I think lacking them in a program which is considered the number one program in statistics is a little bit unjustified.

So I hope I can add the code for the t.test (with only means, SDs, and sample sizes as the input arguments) and perhaps ANOVA and chi-square. But as a super ultra noob in R and also in stats, I think I will need your kind help.
