Error “comparison (6) is possible only for atomic and list types” encountered in metafor

Hi there! I'm very new to r and trying to run a multi-level meta analysis using pre-calculated effect sizes. The data file named 'test run vividness v2' can be accessed via this link:testrunfile

The script I used as a first step to fit the model was:

res <- rma.mv (yi = es_r, v = var, data = testrun, method = "REML", level = 95, digits = 7, slab = ref, random = ~ 1 | samp_id)

But I keep getting this error:

Error in verbose > 2 : comparison (6) is possible only for atomic and list types

Could someone help give me a hand to help me understand what this error message means and where did I go wrong with the script? Many thanks!

What packages are you using?

You need a login to access the data via the link you posted.

Can you provide a reproducible example?

Hi William! Thanks so much for reaching out. I've just made the data file public. You should have no problem accessing it now. Sorry about the oversight.
I'm using the metafor package.

I had a bit of a look, but sorry no idea. Have you had a look at the documentation for metafor? There is a bit in there when you look at ?rma.mv

Thanks William! I'll definitely have a look!
