View source: R/overlapSC.R

Description

The overlapSC function provides the most common overlap indices for single-case data and some additional statistics.

Usage

1
overlapSC(data, decreasing = FALSE, phases = c("A","B"))

Arguments

data

A single-case data frame. See scdf to learn about this format.

decreasing

If you expect data to be lower in the B phase, set decreasing = TRUE. Default is decreasing = FALSE.

phases

A vector of two characters or numbers indicating the two phases that should be compared. E.g., phases = c("A","C") or phases = c(2,4) for comparing the second to the fourth phase. Phases could be combined by providing a list with two elements. E.g., phases = list(A = c(1,3), B = c(2,4)) will compare phases 1 and 3 (as A) against 2 and 4 (as B). Default is phases = c("A","B").

Value

overlap

A data frame consisting of the following indices for each single-case for all cases: PND, PEM, PET, NAP, PAND, Tau-U (A vs. B - Trend A), Diff_mean, Diff_trend, SMD.
