[R] Help on hypothesis testing

I hope to use R to perform some hypothesis testing, such as t.test() and var.test(). 
However, I don't find a function that could do test on means with variance known
(i.e., u test or z test in some textbook), and a function that could do test on 
variances of normal distribution (i.e. chi-squared test).

Thanks in advance for any hints.

Best wishes,
