addcod {DDM}

append a $cod column if missing

Description

Only handles the case of missing $cod splitting variable for data of a single year/region. This is not super robust. If you have many regions or whatever then do it yourself. This function was just written to make ggb() robust to the case of a user specifying data that don't have any territorial or other subgroups, aside from sex.

Usage

addcod(X)

Arguments

X

a data.frame, possibly but not necessarily with column $sex.

Value

X with a new column, $cod appended.
