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

Creating a long format data frame from several single-case data frames (scdf).

Description

The as.data.frame function transposes an scdf into one long data frame. Additionally, a data frame can be merged that includes level 2 data of the subjects. This might be helpful to prepare data to be used with other packages than scan.

Usage

## S3 method for class 'scdf'
as.data.frame(x, ..., l2 = NULL, id = "case")

Arguments

x	An scdf object
...	Not implemented
l2	A data frame providing additional variables at Level 2. The scdf has to have names for all cases and the Level 2 data frame has to have a column with corresponding case names.
id	Variable name of the Level 2 data frame that contains the case names.

Value

Returns one data frame with data of all single-cases structured by the case variable.

Examples

## Convert the list of three single-case data frames from Grosche (2011)
### into one long data frame
Grosche2011
Grosche2011_long <- as.data.frame(Grosche2011)
Grosche2011_long

## Combine an scdf with data for l2
Leidig2018_long <- as.data.frame(Leidig2018, l2 = Leidig2018_l2)
names(Leidig2018_long)
summary(Leidig2018_long)
