Append Empty Columns — append_empty

Appends empty columns (value = NA) to a data.frame.

Usage

append_empty_col(df, col, order = FALSE)

df: A data.frame.
col: The name(s) of one or more columns desired in the final data.frame, as a character vector. Any names not currently in the data.frame will be added as empty columns; those present will remain unchanged.
order: Whether to reorder the data.frame to match the order of col, as a boolean (default: FALSE). If FALSE empty columns are added to the right. When order = TRUE, col is used to specify column order. Thus, in addition to the names of the empty columns to append, col must include all column names in df. append_empty_col() will not subset/select columns.
