[R] refline in forest() {metafor}

[johnwilliams at fas.harvard.edu]

Hello all,

I am using forest.rma to plot a random effects model meta-analysis. I noticed
that refline sets a vertical line indicating the null hypothesis.

Is there a way to draw another vertical line, possibly dashed, centered on the
summary estimate?

Prof. Viechtbauer, if you happen to read this, I'd like to thank you for making
an excellent package. I have been using the metafor package to do my first
meta-analysis, having never used R before. The documentation is thorough and
intuitive.

Thanks,

John
