Mplus not available (Mac)

[Anja Morstatt]

Hi all, 

I am having a hard time getting Mplus and R to connect on my Mac (11.6). 

I'm running RStudio Version 4.1.1, MplusAutomation 1.0.0 and I have already installed XQuartz and I'm not getting any kind of error message when loading the tcltk package... 

Any more ideas what could cause this problem? 

Many thanks :)

Anja

Hi there, Anja,

Do you have Mplus installed on the machine? For example, on my Mac, it's installed here: /Applications/Mplus. You won't be able to use MplusAutomation without this. If you have it installed in a non-standard location, you'll need pass the path to Mplus using the Mplus_command argument of readModels.

Hope this helps,

Michael

Hi Michael, 

thanks for your reply! 

Yes, Mplus is directly installed on the machine. For whatever reason, mplusAvailable() still tells me that its not, but it works now - I am able to run models through R. 

I had some issues with the line breaks in my original input files, but after creating them directly with createModels and a template file, it worked fine now. 

On my first try, I copied a displayed terminal command to my terminal directly and had to grant the terminal access rights to my files - maybe that is interesting for someone else as well. 

In short: It works now, but I don't know why.

Cheers

Anja
