R implementation of the SPSS
a (non-empty) data.frame or input data of class "xpssFrame".
xpssTemporary signals the beginning of temporary transformation. Only the following data-management procedure takes affect on the data: ,
All the changes that are made are temporary. After the next modification the data is restored.
For example: all created variables, e.g. numeric or string variables created while
xpssTemporary is in effect are temporary variables!
Any changes or modifications made to existing variables while the
xpssTemporary command is in effect are also temporary!
Any variables which are created or modified after this procedure are again permanent.
| ||Effect on created variables||Effect on modified variables|
| ||Any created variable is temporary.||Any change on a variables is temporary.|
| ||Any created variable is permanent.||Any change on a variables is permanent.|
The xpssTemporary function allows analyses for subgroups without affecting the data and then repeat the analysis for the file as a whole.
