changeMissings: Change missing code.

In eatGADS: Data Management of Large Hierarchical Data

Change missing code.

Description

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.

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.

Value

Returns the GADSdat object with changed meta data.

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"))
