Add SMART flags to a stratified sample survey (e.g. MICS, DHS, national SMART)

national.SMART(x, strata, indices = c("haz", "whz", "waz"))

Arguments

x	Survey dataset (as an R data.frame) with indices present
strata	Name of column in `x` that defines the strata
indices	Names of columns in `x` containing indices

Value

A data.frame with same structure as x with a flagSMART column added. This column is coded using sums of powers of two

Examples

# Use the national.SMART() function to flag indices from a national
# SMART survey in Nigeria (flag.ex03)
svy <- flag.ex03
svyFlagged <- national.SMART(x = svy, strata = "state")

# Exclude records with flagging codes relevant to whz:
svyFlagged <- svyFlagged[!(svyFlagged$flagSMART %in% c(2, 3, 6, 7)), ]
