Package: drfit
Version: 0.6.4
Date: 2015-10-07
Title: Dose-Response Data Evaluation
Authors@R: c(person("Johannes", "Ranke", role = c("aut", "cre"),
email = "jranke@uni-bremen.de"))
Imports: graphics, grDevices, MASS, drc
Suggests: RODBC
Description: A somewhat outdated package of basic and easy-to-use functions for
fitting dose-response curves to continuous dose-response data, calculating some
(eco)toxicological parameters and plotting the results. Please consider using
the more powerful and actively developed 'drc' package. 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.
