[R-meta] Observed effect size using escalc

It calculates it using one of dozens of formulae depending on what sort
of input you gave it. If you show us the code you have inherited we can
probably help further. The help ?escalc does have wagon-loads of detail
about this if you want to probe further.
When you do post code please set your e-mailer to send plain text as

It appears that the yi vector is an output variable that escalc() appends to the dataset. The metafor documentation says that yi is the observed effect size, and we didn't enter this as an input variable, so I'm wondering what formula escalc() uses to determine yi. Would anyone here have some insight on how yi is calculated?
