Hi Mike,
All of your posts have been extremely helpful. However, I do have a few remaining questions.
I read that it is easier to download the OpenMX and metaSEM packages in RStudio, so that's what I did and I think it worked. I just don't know how to test it - do you have any sample data sets that I could plug into a session to see if it works?
Also, do you recommend sticking with R instead of RStudio? We will be using it for an extensive project and don't want to run into problems down the line if RStudio doesn't work as well as R.
Thanks so much!
