[R-meta] Funnel plot with Egger regression test, using R

[Michael Dewey]

Dear Margot

Unless you absolutely need the meta-analysis too

library(metafor)
funnel(yi = yi, sei = sei)
regtest(yi = yi, sei = sei)

should do it.

There are other parameters to both functions which you can obviously use 
too and which  may help you get just the plot you long for.

And as Gerta said in her reply you can use meta or several other 
packages from CRAN to do it too.
