[R] Metafor - why use escalc?

Dear All



As you can specify the data directly to rma.uni via n1i, m1i, sd1i, etc in
Metafor, why would you ever want to use escalc to calculate yi and vi?
Aren't these just intermediate steps to the final pooled effect size which
is calculated by rma.uni; or is there some advantage to calculating yi and vi
separately using escalc?

Thanks

Ed
