Check SPSS Compliance of Meta Data

Description

Function to check if variable names and labels, value labels and missing codes comply with SPSS requirements for meta data.

Usage

check4SPSS(GADSdat)

Arguments

GADSdat

GADSdat object imported via eatGADS.

Details

The function measures the length of variable names ("varNames_length", maximum of 64 characters) variable labels ("varLabels", maximum of 256 characters), value labels ("valLabels", maximum of 120 characters). Furthermore, missing codes are counted ("missings", maximum of three missing codes for character variables) and special characters are flagged in variable names ("varNames_special"). Check results are reported back on variable level, with the exception of "valLabels", which is a list with entries per violating variable.

Value

Examples

# Change example data set (create a violating label)
pisa2 <- changeVarLabels(pisa, varName = "computer_age",
                        varLabel = paste(rep("3", 125), collapse = ""))

check4SPSS(pisa2)
