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

[JessD]

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?

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…

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!
