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?
