[R-meta] margins command

[Patricia Ziegelmann]

Dear all,

I´m adjusting a simple metaregression model:

meta <- rma(yi = yi,
              sei = vi,
              mods = ~ risk1 + risk2,
              data = data1,
              method = "REML")

Both risk1 and risk2 are binary factors.

Is it possible to estimate a confidence interval for a function of the
fitted coefficients, let's say beta[1]+beta[2]?

Also, is there a command like the "margins" to have marginal effects
summaries?

Thanks in advance for any help,

Patricia
