#' Trout: Hemoglobin in Trouts on Different Diets
#'
#' This is data of the amount of hemoglobin in the blood of 40 brown trouts. The
#' trouts were placed at random in four different throughs (Norwegian: Kar). In
#' each trough the fish food contained different amount of sulfamerazine. The
#' measurements of hemoglobin in g/dl were made on 10 randomly selected
#' fish from each through after 35 days.
#'
#' @format A data frame with 40 observations (rows) and 2 variables (columns).

#' The levels of sulfamerazine, S00, S05, S10 and S15, represents 0g, 5g, 10g,
#' and 15g per 100 pounds of fish food.
