#' World Health Organization TB data
#'
#' @description
#' A subset of data from the World Health Organization Global Tuberculosis
#' Report, and accompanying global populations. `who` uses the original
#' codes from the World Health Organization. The column names for columns
#' 5 through 60 are made by combining `new_` with:
#'
#' * the method of diagnosis (`rel` = relapse, `sn` = negative pulmonary
#'   smear, `sp` = positive pulmonary smear, `ep` = extrapulmonary),
#' * gender (`f` = female, `m` = male), and
#' * age group (`014` = 0-14 yrs of age, `1524` = 15-24, `2534` = 25-34,
#'   `3544` = 35-44 years of age, `4554` = 45-54, `5564` = 55-64,
#'   `65` = 65 years or older).
#'
#' `who2` is a lightly modified version that makes teaching the basics
#' easier by tweaking the variables to be slightly more consistent and
#' dropping `iso2` and `iso3`. `newrel` is replaced by `new_rel`, and a
#' `_` is added after the gender.
#'
#' @format ## `who`
#' A data frame with 7,240 rows and 60 columns:
#' \describe{
#'   \item{country}{Country name}
#'   \item{iso2, iso3}{2 & 3 letter ISO country codes}
#'   \item{year}{Year}
#'   \item{new_sp_m014 - new_rel_f65}{Counts of new TB cases recorded by group.
#'    Column names encode three variables that describe the group.}

#' Example tabular representations
#'
#' Data sets that demonstrate multiple ways to layout the same tabular data.
#'
#' `table1`, `table2`, `table3`, `table4a`, `table4b`,
#' and `table5` all display the number of TB cases documented by the World
#' Health Organization in Afghanistan, Brazil, and China between 1999 and 2000.
#' The data contains values associated with four variables (country, year,
#' cases, and population), but each table organizes the values in a different
#' layout.

#' The data is a subset of the data contained in the World Health
#' Organization Global Tuberculosis Report

#' Fish encounters
#'
#' Information about fish swimming down a river: each station represents an
#' autonomous monitor that records if a tagged fish was seen at that location.
#' Fish travel in one direction (migrating downstream). Information about
#' misses is just as important as hits, but is not directly recorded in this
#' form of the data.
