Hi Andres,
Thank you for your very fast reply! I guess you are right, I think a got a bit thrown off:
I was looking for a solution for the following error, and thought it would be in the metacont function, but I see now that it is not.
The problem is this:
When I try to run the forest() function, I get the following error:
Error in forest.default(MIMAMotorImptot, text.addline1 = "Motor Impairment. Analysis 1", :
Must specify either 'vi', 'sei', or ('ci.lb', 'ci.ub') pairs.
The code that I'm trying to run is the following:
forest(MIMAMotorImptot, text.addline1= "Motor Impairment. Analysis 1", xlab="SMD >0 favours intervention", comb.fixed = TRUE, test.overall.fixed = TRUE, col.fixed="steel blue", col.diamond.fixed = "steel blue", comb.random = TRUE, test.overall.random = TRUE, fontsize = 10, digits.se = 1, digits.mean = 1, col.random = "red", col.diamond.random = "red")
It ran perfectly every time under R version 3.6.1., do you have any ideas what it could be? I've been stuck for the entire afternoon :(( Thank you so much for your help!
