longCatEDA-package: Plot Categorical Longitudinal and Time-Series Data

Description Details Author(s) References Examples

Description

Package to implement horizontal line plots for categorical (ordinal or nominal) longitudinal or time-series data. This is done by mapping individuals to the vertical space (each horizontal line represents a participant), time (or repeated measures) to the horizontal space, categorical (or discrete) states as facets using color or shade, and events to points. Sorting individuals in the vertical space can reveal patterns in changes over time.

Example usage is longCatPlot(longCat(y)) where y is a matrix or data frame in wide format with participants in rows and repeated observations in columns. The function longCat returns an object of class longCat which can be plotted using longCatPlot. Options for sorting and/or stratifying by groups are implemented using sorter which returns a sorted and/or stratified object of class longCat.
