OpenMx Installation

Hi,
on an i7 windows machine, I installed R 2.12.1 and try to install OpenMx from a stick, as the machine has no internet.

I downloaded OpenMx_1.0.6-1581.zip and in R (32 bit version) install using

install.packages(pkgs="d:/camelia/OpenMx_1.0.6-1581.zip",repos=NULL).

The install results in: package OpenMx successfully unpacked and MD5 sums checked.

Library(OpenMx) results in
Error: package 'OpenMx' is not installed for 'arch=i386'

I also tried this with R 2.12.2 (32 bit version).

I though I was following instuctions from a previous response to a similar question.

After sourcing the latest version of OpenMx on a Windows XP machine running R 2.9.2, we get the following error upon 'require(OpenMx):

require(OpenMx)
Loading required package: OpenMx
Error in registerS3method(Info[i, 1], Info[i, 2], Info[i, 3], env) :
no slot of name "methods" for this object of class "derivedDefaultMethod"
In addition: Warning message:
package 'OpenMx' was built under R version 2.11.0

Any suggestions on how to fix this?

Thanks,

Hi

I need to install a OpenMx version that work on 2.10 (as only this version in an avalaible version for Linux on R-CRAN website and we need to test it soon).
I think that openMX 1.0.2 is ok for that. However, I coudl not install it with the
source('http://openmx.psyc.virginia.edu/getOpenMx.R') command
that directly goes to the last openMX version...
how could I do ?
thanks!

ps: I did not find anything related to that question on the forum....

Currently, if you have R 2.11, the installation script installs the OpenMx version compiled for R 2.12 and complains that 2.12 must be installed in order for OpenMx 1.0.3 to run.

I thought we were still supporting 2.11.

Hi,

I tried a model last week that was still running after 4 days and was really consuming too much CPU for efficient computer use. I've got an older Windows box that I don't really use for anything and thought I might just let the models run on that to free up my normal machine. But it's not really connectable to the net to download OpenMx - can you install off a USB drive somehow?

Thanks,

Paul

Hi,

Firstly, thank you very much indeed for your efforts in providing this wonderful tool to the R "community". I'm trying to install it on a 32-bit GNU/Linux environment (Ubuntu Maverick, to be precise) with R 2.12.0. When compiling from source the build fails because it can't find the function or variable "errno". Is there are fix or workaround available? Thanks again,

John

We have found that the default blas (basic linear algebra system) libraries supplied with R for MAC OS X have poor performance. Specifically, the following three commands, executed as root in a Terminal.app window reduces OpenMx execution time by 75% in some cases (ymmv).

cd /Library/Frameworks/R.framework/Libraries
sudo rm libRblas.dylib
sudo ln -s libRblas.0.dylib libRblas.dylib

Note that these commands simply reconfigure the link, they don't actually delete any libraries. To *undo* these commands one could do the following:

cd /Library/Frameworks/R.framework/Libraries

I have observed this for a while in two 32-bit and one 64-bit computers with Fedora 13.

When I installed OpenMx inside R with a root account by source('http://openmx.psyc.virginia.edu/getOpenMx.R'), I got the following errors:

** testing if installed package can be loaded
Error in dyn.load(file, DLLpath = DLLpath, ...) :

any suggestions?

Thank you!!

The R developers are aiming for a release of 2.12.0 sometime this fall. Here's what I would like to do with the OpenMx binary releases when the new version of R is released.
