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,
