If I do
source('https://openmx.ssri.psu.edu/getOpenMx.R')
the result is
You are now installing OpenMx 2.0. OpenMx 2.0 has a number of exciting new features, described in more detail at https://openmx.ssri.psu.edu/2014/10/openmx-version-20-officially-released and in the OpenMx User's Guide. Most OpenMx-1.4 scripts will work under OpenMx 2.0, but users who wish to download and install the previous stable version can run source('https://openmx.ssri.psu.edu/getOpenMx1.R') instead. We will only be maintaining getOpenMx1.R for a short while, so we do encourage you to upgrade soon! trying URL 'http://ftp5.gwdg.de/pub/misc/cran/src/contrib/OpenMx_2.2.2.tgz' Warning in install.packages : cannot open: HTTP status was '404 Not Found' Error in download.file(url, destfile, method, mode = "wb", ...) : cannot open URL 'http://ftp5.gwdg.de/pub/misc/cran/src/contrib/OpenMx_2.2.2.tgz' Warning in install.packages : download of package 'OpenMx' failed
