Meta-regression with two control variables in R

Hi there,

I want to calculate meta regressions with the meta package in R. But the regression must be controlled for two variables x and y. Does anyone know how I can bring my control variable into the calculations?

`meta_regr <- metareg(meta_analysis, ~year)`

Thanks for your help!


Less is more. Stay pure. Stay poor.
I have not used meta reg yet, but this interests me. On Monday I may investigate!

Have you used meta reg in a bivariate scenario before?
