1.594152e-01 / sqrt(8.248391e + 01*2.264225e-03) = 0.37

in the original formula genetic correlation is covariance of two variables divided by square roots of their variances. In here it is a some kind of variance between bden and velov that can be transformed to variance by root square? Or is there any other explanation. Covariance is a square root of variance, is not it?

]]>Looking forward to your help!

]]>Glad to see an example for efficient management of datasets on R. I usually write long (and probably inefficient) chunks of code for manipulating and merging my datasets. I was wondering if you could share part of the datasets you used here to replicate the code (and understand better the differences).

Thanks!
