extract_standard(.data, concentration = "concentration", od = "od", std_key = "^STD", dec = ".", var_in = "value")
| .data | dataframe containing at least the value and id columns (with O.D. values and sample identifiers). |
|---|---|
| concentration | name of the concentration column |
| od | name of the O.D. column |
| std_key | a character string specifying the common starting pattern of standard point ids (default = "^STD"). |
| dec | a character string used as a decimal separator for the encoded standard concentration values. |
| var_in | a character string used for the OD values (default = "value") |
