Metafor

This is a question of clarification.
IN 2009 Higgins, Thompson and Spiegelhalter (J R Statist Soc A 172:137-159) gave WinBUGs code to get credible intervals from random effects meta analysis for the prediction interval of a new study.
It appears that the predict.rma function creates approximate credible intervals (pending a function revision by the author) for that purpose.

Multivariate binary response analysis

Greetings ~
I need some assistance determining an appropriate approach to analyzing multivariate binary response data, and how to do it in R.
The setting: Data from an assay, wherein 6-hours-post-fertilization zebrafish embryos (n=20, say) are exposed in a vial to a chemical (replicated 3 times, say), and 5 days later observed for the presence/absence (1/0) of defects in several organ
