[R] meta-analysis question

[Remko Duursma]

Dear R-helpers,

i have the following situation: i have a bunch of y=b0 + b1*x from different studies, and want to estimate a "general" y=f(x). I only have the b0,b1's and R-squareds. Should i weigh the separate equations by their R-squared? 

thanks

Remko
