[R-meta] how to get vcalc from metafor

Hi Wolfgang, 

I realised I already had the remotes package installed, 
and when I ran the second line 

remotes::install_github("wviechtb/metafor") 

on its own it worked. 

Thank you ! 

Best wishes, 
Norman.

Hi Normand, 

vcalc() is currently only part of the devel version of metafor, so you indeed would need to do: 

install.packages("remotes") 
remotes::install_github("wviechtb/metafor") 

Best to do this in a fresh R session. If it doesn't work, then you will have to be more concrete as to the error messages you get when trying this. 

Best, 
Wolfgang

Dear list members, 

I recently read a thread in which the vcalc() function from metafor was mentioned 
and I tried to use it, but Rstudio tells me it can't find the vcalc function. 

I tried re-installing metafor through the "install" button and then i used the 
following lines 

install.packages("remotes") 
remotes::install_github("wviechtb/metafor") 

but neither method made it work. 

Any advice please ? 

Best wishes, 
Norman.
