Dear R-help, Can someone please help me discover what function or code will give me a p-value from the input: 1) R-square statistic from a simple linear regression, and 2) sample size, n This would be greatly appreciated. I need this because I am using a database that gives me R-square and sample size for multiple comparisons, and I wish to determine the false discovery rate using q-value. Thanks again, Justin S.

and you'll see that the object returned from summary has the two common R^2
measures, as well as things like residuals from which can compute n quite
easily -- which you could obviously also from your regressors and regressand.
