This code worked for me:

library("devtools")

devtools::install_github("MathiasHarrer/dmetar")

Not working

Hi

--metafor

--metaSEM

I use both as both deliver distinct information.

All the best,

--Holger

Hello,

I would like to add one more potential r package:

--robumeta

It is quite straight forward, but less adaptive than say metafor.

Best,

Valentin

you need to run this code in the console dear

install.packages("devtools")

library("devtools")

devtools::install_github("MathiasHarrer/dmetar")

library("dmeta")

if still not working go to the file where you save the packages and delete all of them and reinstall the R and try again

if (!require("devtools")) {

install.packages("devtools") }

devtools::install_github("MathiasHarrer/dmetar")@
