AdhereR: an R package for computing adherence to medications and for visualising medication histories

Build Status

This is a package for the R open-source statistical environment implementing various ways of computing adherence to medications and visualisations of medication histories, both interactive (intended for data exploration) and high quality (intended for publication).

More information is given in the package's various vignettes and in the accompanying paper:

Dima AL, Dediu D (2017). Computation of adherence to medication and visualization of medication histories in R with AdhereR: Towards transparent and reproducible use of electronic healthcare data. PLoS ONE, 12(4): e0174426. doi:10.1371/journal.pone.0174426

While the package can be created from the source or installed using the source package AdhereR_X.tar.gz provided in this repository (where X refers to the package's version), we recommend that users install it directly from The Comprehensive R Archive Network (CRAN) using the normal procedure1 (i.e., install.packages("AdhereR", dep=TRUE)).

The package is implemented in pure R, but optimised to work on mid-range hardware even for large databases (stored, for example, in an SQL RDBMS), single-threaded or parallelized in large heterogeneous clusters (using, for example, Apache Hadoop), and runs on any platform that supports R. A standardized interface allows AdhereR to be used transparently from other programming languages or platforms, and a fully functional bridge to Psython 3 is provided as an example. The code is released under GPL v3.

Feedback is welcome either directly by e-mailing us or by using GitHub's system for bug reporting and suggestions.
