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 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.
- I would be delighted if you would join in this effort of creating useful
- and useable tools for dealing with dose-response data from biological
- testing.
