vars

A character vector of column names, or a single string of space-separated names, e.g. "age ht wt bmi".

Value

A data frame containing only the requested columns in the requested order.

Details

vars may be supplied as a character vector or as a single space-separated string (matching the Var_CatList / Var_ContList style from the template).
