OpenMx Installation

As of revision 808 in the subversion repository, snow and snowfall are now optional packages. If they have been loaded prior to running a model, then independent submodels will be executed in parallel. Otherwise sequential execution occurs. We can update the installer in the next closed beta release (0.1.4) to not download these packages.

Hi,
I encountered an error while attempting to install on my Ubuntu 9.04 machine. The error message and system info are below, but here is a summary of the problem:

The installation procedure called by source(REDACTED) is trying to download the file REDACTED/OpenMx_0.1.3-776.tar.gz, but this file does not exist. I manually downloaded REDACTED/OpenMx_0.1.3-776.tgz (note .tar.gz vs .tgz) and installed it with R CMD INSTALL. Everything appears to be fine, so I think all is needed is to fix the file name suffix.

-Ista

Errors and system info follow:
source('REDACTED')

This message is generated by the snowfall package when loading the OpenMx library in the OS X graphical user interface. It's a harmless message, and users should just ignore it. I've submitted a 3 line patch to the maintainer of the snowfall package, so we hope this message will go away in the next release of snowfall. If you want to download the snowfall source yourself (version 1.70), I've attached the patch to this post.

Am I missing a step? Did source('http://...'), library(OpenMx) and problems came up.

Welcome to the OpenMx Installation Forum. If you're here, you may be having problems installing OpenMx, but we're here to help. The first step is install R (http://r-project.org). You need to make sure that you have version 2.9.1 or the latest version as of August 2, 2009. Next, you need to run the command that Steve included in his email. That will install the dependencies required for OpenMx, namely Snowfall, and download and install the version of OpenMx that will work with your system.
