Hi all,

I would like to use "extract_eq" command in the "equatiomatic" package,
I managed to install the package but cannot open it. Below is what I got. Please help!

library(equatiomatic)

Hi again all,
I noticed that the R version I had is too old for the "equatiomatic" package. I updated R from CRAN mirror and it solves the problem.
