Title: Dose-response data evaluation
Authors@R: c(person("Johannes", "Ranke", role = c("aut", "cre"),

Imports: MASS, RODBC, drc
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 density 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. As an alternative to the original fitting methods, the
algorithms from the drc package can be used.
