ADNIMERGE data package for R

For users of R, we have developed a data package "ADNIMERGE" which contains coded data, documentation, and analysis vignettes. The package documentation can be found at http://adni.bitbucket.org/ and more information about ADNI is available from http://adni.loni.usc.edu/. The R package depends on Frank Harrrel's Hmisc package which can be installed from the R package repository (CRAN) by:

R prompt> install.packages("Hmisc")

To downloading the compressed ADNIMERGE_0.0.1.tar.gz file, direct your browser to

http://adni.loni.usc.edu/ > Login > Download > Study Info > Merged ADNI 1/GO/2 Package for R

The package can be installed to your R system by entering the following at an R prompt:

R prompt> install.packages("ADNIMERGE_0.0.1.tar.gz", repos = NULL, type = "source")

If you have trouble installing, more information can be found here.
