[R] how to find critical values of t in R

Hi,

I am trying to find a function in R that would calculate the critical value of t for a given probability and df. For example, if p=5% and df=20, then does R have a function to calculate the t value? I tried:

> dt(0.05,df=20)

[1] 0.3934718

That doesn't look right to me. Could someone tell me what I was missing?

Thanks,
