-#' Pre-Defined Dose Frequencies
-#'
-#' @description
-#' These pre-defined dose frequencies are sourced from
-#' [CDISC](https://evs.nci.nih.gov/ftp1/CDISC/SDTM/SDTM%20Terminology.pdf). The
-#' number of rows to generate using `create_single_dose_dataset()` arguments
-#' `start_date` and `end_date` is derived from `DOSE_COUNT`, `DOSE_WINDOW`, and
-#' `CONVERSION_FACTOR` with appropriate functions from `lubridate`.
-#'
-#' @details
-#' `NCI_CODE` and `CDISC_VALUE` are included from the CDISC source for
-#' traceability.
-#'
-#' `DOSE_COUNT` represents the number of doses received in one single unit of
-#' `DOSE_WINDOW`. For example, for `CDISC_VALUE=="10 DAYS PER MONTH"`,
-#' `DOSE_WINDOW=="MONTH"` and `DOSE_COUNT==10`. Similarly, for
-#' `CDISC_VALUE=="EVERY 2 WEEKS"`, `DOSE_WINDOW=="WEEK"` and
-#' `DOSE_COUNT==0.5` (to yield one dose every two weeks).
-#'
-#' `CONVERSION_FACTOR` is used to convert `DOSE_WINDOW` units `"WEEK"`,
-#'  `"MONTH"`, and `"YEAR"` to the unit `"DAY"`.
-#'
-#' For example, for `CDISC_VALUE=="10 DAYS PER MONTH"`, `CONVERSION_FACTOR`
-#' is `0.0329`. One day of a month is assumed to be `1 / 30.4375` of a month (one
-#' day is assumed to be `1/365.25` of a year).
-#' Given only `start_date` and `end_date` in the aggregate dataset, `CONVERSION_FACTOR`
-#' is used to calculate specific dates for`start_date` and `end_date` in the
-#' resulting single dose dataset for the doses that occur. In such cases, doses
-#' are assumed to occur at evenly spaced increments over the interval.
-#'
-#'
-#' To see the entire table in the console, run `print(dose_freq_lookup)`.
