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('http://openmx.psyc.virginia.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

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:

R version 2.14.2 (2012-02-29)
Copyright (C) 2012 The R Foundation for Statistical Computing
ISBN 3-900051-07-0
Platform: i386-pc-mingw32/i386 (32-bit)

R is a collaborative project with many contributors.
Type 'contributors()' for more information and
'citation()' on how to cite R or R packages in publications.
 
Type 'demo()' for some demos, 'help()' for on-line help, or
'help.start()' for an HTML browser interface to help.
Type 'q()' to quit R.

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?
