For users of R, we have developed a data package “ADNIMERGE” which contains coded data, documentation, and analysis vignettes. It depends on Frank Harrrel’s Hmisc package which can be installed from the R package repository (CRAN) by:

R prompt> install.packages("Hmisc")

After downloading the compressed ADNIMERGE_0.0.1.tar.gz file, it can be installed to your R system by entering the following at an R prompt:

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

If you have trouble installing, more information can be found at

To browse document and analysis vignettes,

R prompt> help(package = "ADNIMERGE")

To view, for example, documentation for the adas:

R prompt> ?adas
