The second argument (called 'vi') in rma() is for the variances. If you have SEs, then use the 'sei' argument:

res <- rma(HR, sei=SE, data=a)

Subject: [R] differences between meat and metafor packages

Hi all;

I have got different results (CI and Q value for heterogeneity, tau) on the
same data when I run meta and metafor for hazard ratio with a random
effects model. The basic programs for both are given below. What can cause?


 res <- rma(HR, SE, data=a)
predict(res, transf=exp)

 metagen(HR, SE, sm="HR", data=a)
