First of all, I'm a physicist and therefore I'm not much used to use statistics. So, please forgive me if this is a FAQ or stupid, but I failed to find the answer by myself.

I want to use corr.test to test for the correlation of two data sets (actually I have a lot of data set and perform pairwise testing). But I wanted to find sets where the correlation is less than a certain limit, i.e. |r_exp| < r_0. As far as I can see corr.test is designed to work only for the null hypothesis r_exp = 0. I would need H0 as |r_exp|>= r_0.

Is there any way to specify this null-hypothesis to corr.test ? Any other idea how to test that hypothesis?
