The Esmpack Package for R

The esmpack package is an add-on package for the statistical software R and consists of a collection of functions that are meant to facilitate the preparation, management, visualization, and analysis of data collected via the experience sampling method (ESM) and ecological momentary assessment (EMA). Its development started at the 2019 ESM Expert Network Meeting in Tilburg. At the moment, the package is still in a rudimentary state, but already contains some useful functions, for example for creating person mean-centered variables, lagging variables, computing the average of several items measuring the same construct, and conducting various data checks.
