title: Getting a p value from a t statistic
body: <p>I'm comparing a long list of observations for two groups, and I have the t statistic and the degrees of freedom for each observation, but I don't actually have the original data. Despite that, I would like to get the p value associated with the t statistic. I know this is possible, but I can't figure out how to get R to report back a p value. Any advice?</p>
