R package

MADRaT provides a framework which should improve reproducibility and transparency in data processing. It provides functionality such as automatic meta data creation and management, rudimentary quality management, data caching, work-flow management and data aggregation.

The last official release of the package can be directly installed from official CRAN repository:

install.packages("madrat")

For installation of the most recent package version an additional repository has to be added in R:

options(repos = c(CRAN = "@CRAN@", rd3mod_repo = "https://www.pik-potsdam.de/rd3mod/R/"))

The additional repository can be made availably permanently by adding the line above to a file called .Rprofile stored in the home folder of your system (Sys.glob("~") in R returns the home directory).

After that the most recent version of the package can be installed using install.packages:

install.packages("madrat")

Package updates can be installed using update.packages (make sure that the additional repository has been added before running that command):

update.packages()

The package comes with a vignette describing the basic functionality of the package and how to use it. You can load it with the following command (the package needs to be installed):

vignette("madrat")

¹ The title is a wish not a promise. By no means we expect this package to deliver everything what is needed to achieve full reproducibility and transparency, but we believe that it supports efforts in this direction.
