  evaluate_1L_lgl = FALSE
)

data_lookup_tb

Data lookup (a tibble)

match_value_xx

Match value (an output object of multiple potential types)

match_var_nm_1L_chr

Match variable name (a character vector of length one)

target_var_nm_1L_chr

Target variable name (a character vector of length one)

evaluate_1L_lgl
