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

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 "rcalc()" may not be suitable for cases
where there are multiple time points or samples etc.

Thank you for your time in advance.
