[R-meta] Calculation of p values in selmodel

[Will Hopkins]

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.
