[R-meta] metafor::rcalc() vcalc() for correlated Pearson rs

[Yuhang Hu]

Hello Everyone,

I'm meta-analyzing the correlation (Pearson r) between extroversion (ext)
and achievement in math, reading, and arts.

My data looks like what is shown below. I wonder whether --rcalc()-- is a
suitable option for building a var-covariance matrix for Pearson r
coefficients in each study OR --vcalc()-- is a more suitable option?

ps. It seems --rcalc()-- requires var1 and var2 in each row to be distinct
in each study which makes me think var1 and var2 must be ID variables.

Thank you for your time in advance.

Sincerely,
Yuhang
