Creating a long format data frame from several single-case data frames (scdf).
The longSCDF function transposes a scdf into one long data frame. Additionally, a data frame can be merged that includes data of the subjects. This might be helpful to prepare data to be used with other packages than scan.
longSCDF(data, l2 = NULL, id = "case")
data |
A single-case data frame. See |
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. |
Returns one data frame with data of all single-cases structured by the case variable.

## Convert the list of three single-case data frames from Grosche (2011) into one long data frame Grosche2011 Grosche2011_long <- longSCDF(Grosche2011) Grosche2011_long ## Combine an scdf with data for l2 Leidig2018_long <- longSCDF(Leidig2018, l2 = Leidig2018_l2) names(Leidig2018_long) summary(Leidig2018_long)
