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.
