This post illustrates how the fxl R package can be used to provide in-depth visual representations of procedural fidelity in single-case experimental designs. This post demonstrates how researchers can visually represent the degree to which a treatment or protocol was applied as designed across a study. The goal of this post is to provide a simple demonstration that could be easily incorporated in applied research as a supplement or replacement to overall fidelity aggregates.

This post focuses on exploring how single-case experimental design (SCED) researchers can use R to visually synthesize experimental outcomes using the Single Case Assessment and Review Framework (SCARF). Specifically, the fxl R package is used to take data coded using SCARF and to generate figures that would historically be prepared using complex Excel spreadsheets. This is not a tutorial on SCARF per se, but rather a demonstration of how fxl supports a spreadsheet-free alternative for users of SCARF.

This entry covers one of the more challenging issues with designing single-case visuals: having many individuals with distinct ranges and patterns in data. This guide shows how to visualize competing selections, with changes in contexts (i.e., transitions in Phase ), with wrapping facets. Facet-specific styling is also modeled/demonstrated in this post.

This post/guide shows how to create a figure that shows how to dynamically create figures to show information that otherwise would require two or more figures. This guide shows how to overlay a Bar Series over a Multielement chart to simultaneously communicate information about internal validity as well as the presence of some functional relationship.
