In growthrates: Estimate Growth Rates from Experimental Data

#' Plate Reader Data of Bacterial Growth
#'
#' Example data set from growth experiments with different
#' concentrations of antibiotics.
#'
#' This rather 'difficult' data set was intentionally selected to make model
#' fitting by the package more challenging.
#'
#' @format Data frame with the following columns:
#' \describe{
#'   \item{strain}{identifier of the bacterial strain, D=donor, R=recipient, T=transconjugant.}
#'   \item{replicate}{replicate of the trial.}
#'   \item{conc}{concentration of the antibiotics (Tetracycline).}
#'   \item{time}{time in hours.}
#'   \item{value}{bacteria concentration measured as optical density.}
