Details

Applied to a GADSdat or all_GADSdat object, this function is a wrapper of getChangeMeta and applyChangeMeta.

SPSS format is supplied following SPSS logic. 'A' represents character variables, 'F' represents numeric variables. The number following this letter represents the maximum width. Optionally, another number can be added after a dot, representing the number of decimals in case of a numeric variable. For instance, 'F8.2' is used for a numeric variable with a maximum width of 8 with 2 decimal numbers.

Examples

# change SPSS format for a single variable (numeric variable with no decimals)
pisa2 <- changeSPSSformat(pisa, varName = "idstud",
                          format = "F10.0")

# change SPSS format for multiple variables (numeric variable with no decimals)
pisa2 <- changeSPSSformat(pisa, varName = c("idstud", "idschool"),
                          format = "F10.0")
