[R] Code for funnel plot

[De Simone]

Hi,

I am using R 4.1, and I am trying to create a funnel plot for continuous
data (measure = mean difference), using metafor. I checked the site
https://www.metafor-project.org/doku.php/plots:funnel_plot_variations, and
code provided is for dichotomous data - measure OR.

res <- rma(yi, vi, data=dat.hackshaw1998, measure="OR", method="EE")

funnel(res, main="Standard Error",back = "lightblue")

My question is how to construct a code to get a funnel for my continuous
data? I am using DL method

Thank you
