Title: Dose-response data evaluation
Author: Johannes Ranke <jranke@uni-bremen.de>
Maintainer: Johannes Ranke <jranke@uni-bremen.de>
Depends: R (>= 2.1.0),stats,RODBC
Description: drfit provides basic and easy-to-use functions for fitting
dose-response curves to dose-response data, calculating some
(eco)toxicological parameters and plotting the results. Functions that are
fitted are the cumulative densitiy function of the lognormal distribution
(probit fit), of the logistic distribution (logit fit), of the weibull
distribution (weibull fit) and a linear-logistic model ("linlogit" fit),
derived from the latter, which is used to describe data showing stimulation
at low doses (hormesis).
In addition, functions checking, plotting and retrieving dose-response data
retrieved from a database accessed via RODBC are included.
