select_phases: Select and combine phases for overlap analyses

In scan: Single-Case Data Analyses for Single and Multiple Baseline Designs

Select and combine phases for overlap analyses

Description

Useful when working with pipe operators. This function allows to select and combine specific phases from an scdf for overlap analyses. For example, in an ABAB design one might want to combine both A phases and both B phases (e.g., A = c(1, 3), B = c(2, 4)). The resulting scdf can then be used in overlap functions such as overlap().

Usage

select_phases(data, A, B, phase_names = "auto")

Arguments

data	A single-case data frame. See scdf() to learn about this format.
A	Selection of the A phase
B	Selection of the B phase
phase_names	A character vector with names for the resulting phases. The default "auto" generates phase names from the combination of the names of the recombined phases.

Details

This function selects and combines the specified phases from the input scdf and returns the resulting scdf with the selected phases only. This is particularly useful when working with pipe operators, allowing to select and combine phases before applying overlap functions. The resulting scdf contains only the selected and combined phases, with phase labels "A" and "B". If phase_names = "auto", phase names are generated from the combination of the names of the recombined phases. For example, combining phases 1 and 3 will result in the phase name "1_3". This function simplifies the process of preparing data for overlap analyses by allowing users to easily select and combine phases in a single step.

Value

An scdf with selected phases
