drexplorer: Dose-response Explorer

#' Dose-response Explorer
#'
#' There is a great variety of models developed for dose-response
#'    data, many of which have been implemented in the drc and DoseFinding
#'    packages. drexplorer combines both packages to aid the user to visually
#'    examine and compare how existing models perform on the data. Another
#'    important feature for drexplorer is to allow the user to identify outlier
#'    measurements and visually examine how these outliers affect the fitted
#'    model.
