recodeNA2missing: Recode NAs to Missing.

Description

Recode NAs in multiple variables in a GADSdat to a numeric value with a value label and a missing tag.

Usage

recodeNA2missing(
  GADSdat,
  recodeVars = namesGADS(GADSdat),
  value = -99,
  valLabel = "missing"
)

Value

Returns the recoded GADSdat.

Arguments

GADSdat

A GADSdat object.

recodeVars

Character vector of variable names which should be recoded.

value

Which value should NAs be recoded to?

valLabel

Which value label should value be assigned?

Details

The value label and missing tag are only added to variables which contain NAs and which have been recoded. If a variable has an existing value label for value, the existing value label is overwritten and a missing tag is added. A corresponding warning is issued.

Examples

# create example GADS
dat <- data.frame(ID = 1:4, age = c(NA, 18, 21, 23),
                  siblings = c(0, 2, NA, NA))
gads <- import_DF(dat)

# recode NAs
gads2 <- recodeNA2missing(gads)
