[R] metafor all list elements must be square matrices

[Michael Dewey]

Dear Hugh

1 - Your post is unreadable because you posted in HTML so it will be 
very difficult for anyone to see your V

2 - there is a separate mailing list for meta-analysis in R where you 
may get more helpful responses as it is monitored by authors of most of 
the main packages. Please see 
https://stat.ethz.ch/mailman/listinfo/r-sig-meta-analysis// and remember 
to register first.
