palmsplusr is an extension to the Personal Activity Location Measurement System (PALMS). This R package provides a customisable platform to combine PALMS data with other sources of information (e.g., shapefiles or csv files). This enables physical activity researchers to answer higher-level questions, such as:
The PALMS data are combined with other input files to build the palmsplus simple features data frame. This can then be summarised two ways:
days provides a breakdown of information per day, per person (e.g., time spent in greenspace)
trajectories builds individual trips, and provides trip-level summaries (e.g., MVPA during the work commute). This can then be processed into multimodal trips if desired.
The user is able to specify how each data source is combined. This is done by creating
field tables using highly customisable formulas.
