eatGADS (version 1.1.1)

inspectMetaDifferences: Inspect meta data differences in a variable.

Description

Inspect meta data differences within a single GADSdat or between two GADSdat objects or GADSdat data bases regarding a specific variable.

Usage

inspectMetaDifferences(
  GADSdat,
  varName,
  other_GADSdat = GADSdat,
  other_varName = varName
)

Value

A list.

Arguments

GADSdat

A GADSdat object.

varName

A character vector of length 1 containing the variable name.

other_GADSdat

A second GADSdat object. If omitted, it is assumed that both variables are part of the first GADSdat.

other_varName

A character vector of length 1 containing the other variable name. If omitted, it is assumed that both variables have identical names (as supplied in varName).

Details

Two GADSdat objects can be compared using equalGADS. If meta data differences for specific variables in the two objects occur, these variables can be further inspected using inspectMetaDifferences. For data-level differences for a specific variable, see inspectDifferences.

Examples

# create a second GADS with different meta data
pisa2 <- pisa
pisa2 <- changeVarLabels(pisa2, varName = "sameteach", varLabel = "Same math teacher")
pisa2 <- recodeGADS(pisa2, varName = "sameteach", oldValues = c(1, 2), newValues = c(0, 1))

# inspect via equalGADS()
equalGADS(pisa, pisa2)

# inspect via inspectMetaDifferences()
inspectMetaDifferences(GADSdat = pisa, varName = "sameteach", other_GADSdat = pisa2)
