[R] Issue with 95% CI using MASS{confint}

[Jennifer Sweatman]

Hi all,

Thank you for your responses. Unfortunately, setting level=0.9500001 or
0.949999 did not work for me. I followed your code, Duncan, and some of my
tau values are less than 2.  I don't know how to interpret this
information, however. Can you point me in the direction to a reference?

Thanks,

Jenn
