Check Value Labels

Check value labels for (a) value labels with no occurrence in the data (checkEmptyValLabels) and (b) values with no value labels (checkMissingValLabels).

Usage

checkEmptyValLabels(
  GADSdat,
  vars = namesGADS(GADSdat),
  valueRange = NULL,
  output = c("list", "data.frame")
)

checkMissingValLabels(
  GADSdat,
  vars = namesGADS(GADSdat),
  classes = c("integer"),
  valueRange = NULL,
  output = c("list", "data.frame")
)

Arguments

GADSdat

A GADSdat object.

vars

Character vector with the variable names to which checkValLabels() should be applied.

valueRange

[optional] Numeric vector of length 2: In which range should numeric values be checked? If specified, only numeric values are returned and strings are omitted.

output

Should the output be structured as a "list" or a "data.frame"?

classes

Character vector with the classes to which checkMissingLabels() should be applied. Valid options are "integer", "double", and "character".

Value

Returns a list of length vars or a data.frame.

Details

NAs are excluded from this check. Designated missing codes are reported normally.

Functions

• checkEmptyValLabels(): check for superfluous value labels

• checkMissingValLabels(): check for missing value labels

Examples

# Check a categorical and a metric variable
checkMissingValLabels(pisa, vars = c("g8g9", "age"))
#> $g8g9
#> NULL
#> 
checkEmptyValLabels(pisa, vars = c("g8g9", "age"))
#> $g8g9
#> NULL
#> 
#> $age
#> NULL
#> 

# Check while defining a specific value range
checkMissingValLabels(pisa, vars = c("g8g9", "age", "idschool"),
              valueRange = c(0, 5))
#> $g8g9
#> NULL
#> 
#> $idschool
#> $idschool$varLabel
#> [1] "School-ID"
#> 
#> $idschool$missing_labels
#> [1] 2 3 4 5
#> 
#> 
checkEmptyValLabels(pisa, vars = c("g8g9", "age", "idschool"),
              valueRange = c(0, 5))
#> $g8g9
#> NULL
#> 
#> $age
#> NULL
#> 
#> $idschool
#> NULL
