Hi, I'm a new user with an extremely basic installation question. Basically, the installation instructions provided on the website say:
"open up an R session and copy the following line into the R command line and press return.
source('https://openmx.ssri.psu.edu/getOpenMx.R')
A few lines of R output will scroll by and you will be asked which type of OpenMx Installation you would like. "
I've successfully downloaded the binary packages, but it does not prompt me to select which type of installation I would like. Instead, what I have is a .zip file containing all the openMX files, but I don't know how to successfully install them. Can I do this through R?
I'm using the most recent version of R (2.15.2).
Thanks for your help!
Hi and welcome to R and OpenMx!
The instructions say to open an R session. That is, launch R. You should get an R window with a splash screen something like this:
Then at the ">" type:
source('http://openmx.psyc.virginia.edu/getOpenMx.R')
This should download and install OpenMx for you.
Then you can load the package in your R session by typing
require(OpenMx)
And check help pages, e.g. for an mxModel
?mxModel
Does that help clarify?
