ez.label.get: get variable label, wrapper of 'sjmisc_get_label'

In jerryzhujian9/zmisc: ez Zhu's miscellaneous functions

get variable label, wrapper of sjmisc_get_label

Description

get variable label, wrapper of sjmisc_get_label

Usage

ez.label.get(x, col = NULL)

ez.getlabel(x, col = NULL)

Arguments

x	a df: (efc), or a single var: (efc$e42dep)
col	evaluated by ez.selcol(x,col). Or, NULL=all cols. returns only labels for specified cols of the df (ignored if x is a var)

Value

returns a named character vector (if x is df), or character (if x is a single var)
If df has no variable label for all variables or for specified cols, returns NULL. If df has label for some variables, returns a string vector with some "".
If a single variable has no label, returns NULL

Note

if df uses foreign style 'variable.labels' and
because of renaming, new col name is not in 'variable.labels',
the function will not retrieve label for that new col name during the process, which is obvious
