Thank you! Unfortunately I still get the warning...
 Extra argument ('pval') disregarded.
...with every invocation of selmodel.

Here?s the line of code involving pval:
    result <- metafor::selmodel(x,  type="step", steps=(0.025),
pval=meta_data$pValue)

It's reading the variable meta_data$pValue OK, because if I make it
meta_data$junk, I get this:
There were 50 or more warnings (use warnings() to see the first 50)
Browse[1]> Q

warnings()

Warning messages:
1: Unknown or uninitialised column: `junk`.
2: Extra argument ('pval') disregarded.
etc.

I closed R and reopened it, but still no joy. I had already restarted R prior to
install.

Wolfgang, I figured that I might be able to implement your
selmodel(...,
pval=dat$pValue) by reverting to for-loop processing. I solved the
previous problems I had with this approach by stripping out the NULLs
from the list objects, so the simulations are running nicely.

However, it appears that the latest version of metafor, which I have
just installed, does not have the pval functionality yet, because I
get this warning with every invocation of selmodel:
Extra argument ('pval') disregarded.

I am still a newbie with R, so I may have done something wrong with
the update process. I got this warning, and nine others like it, but I
presume this doesn't apply to metafor:
Warning: package 'boot' in library 'C:/Program
Files/R/R-4.3.2/library' will not be updated.

I then got this, again presumably irrelevant:
Warning: cannot remove prior installation of package ?lattice?
Warning: restored ?lattice?

The only warning for loading metafor was this:
package ?Matrix? was built under R version 4.3.3

The other possibility is that my for-loop processing has some kind of
mistake, but it seems to be OK. Each loop produces a meta-analysis
object resultmeta from invocation of ram.uni with a dataset meta_data
(the i-th subset of my full dataset). I then apply selmodel to
resultmeta within a function, where the x is
resultmeta:
result <- metafor::selmodel(x,  type="step", steps=(0.025),
pval=meta_data$pValue)

I give up. Help, please!
