Change missing code.

Change or add missing codes of one or multiple variables as part of a GADSdat object.

Usage

changeMissings(GADSdat, varName, value, missings)

Arguments

GADSdat

GADSdat object imported via eatGADS.

varName

Character vector containing variable names.

value

Numeric values.

missings

Character vector of the new missing codes, either "miss" or "valid". Missings tags are applied in the same ordering as value.

Value

Returns the GADSdat object with changed meta data.

Details

Applied to a GADSdat or all_GADSdat object, this function is a wrapper of getChangeMeta and applyChangeMeta. The function supports changing multiple missing tags (missings) as well as missing tags of multiple variables (varName) at once.

Examples

# Set a specific value to missing
pisa2 <- changeMissings(pisa, varName = "computer_age",
                        value = 5, missings = "miss")

# Set multiple values to missing
pisa3 <- changeMissings(pisa, varName = "computer_age",
                        value = 1:4,
                        missings = c("miss", "miss", "miss", "miss"))

# Set a specific value to not missing
pisa4 <- changeMissings(pisa2, varName = "computer_age",
                        value = 5, missings = "valid")

# Add missing tags to multiple variables
pisa5 <- changeMissings(pisa, varName = c("g8g9", "computer_age"),
                        value = c(-99, -98), missings = c("miss", "miss"))
