2014). Includes a function for conveniently defining differential equation
models, model solution based on eigenvalues if possible or using numerical
solvers. If a C compiler (on windows: 'Rtools') is installed, differential
equation models are solved using automatically generated C functions.
Heteroscedasticity can be taken into account using variance by variable or
two-component error models as described by Ranke and Meinecke (2018)
<doi:10.3390/environments6120124>. Hierarchical degradation models can
be fitted using nonlinear mixed-effects model packages as a backend as
described by Ranke et al. (2021) <doi:10.3390/environments8080071>. Please
note that no warranty is implied for correctness of results or fitness for a
particular purpose.https://github.com/r-universe/jranke/actions/runs/4429784149Tue, 14 Mar 2023 19:10:25 GMTmkin1.2.3successhttps://jranke.r-universe.devhttps://github.com/jranke/mkintwa.rmdtwa.htmlCalculation of time weighted average concentrations with mkin2017-03-04 08:58:002021-02-15 14:20:53FOCUS_D.rmdFOCUS_D.htmlExample evaluation of FOCUS Example Dataset D2020-05-13 14:20:232021-02-15 14:20:53FOCUS_L.rmdFOCUS_L.htmlExample evaluation of FOCUS Laboratory Data L1 to L32020-05-13 14:20:232022-07-01 07:08:49mkin.rmdmkin.htmlmkin - Kinetic evaluation of chemical degradation data2020-05-13 14:20:232022-02-08 16:17:29dmta_parent_2022_prebuilt.rnwdmta_parent_2022_prebuilt.pdfTesting hierarchical parent degradation kinetics with residue data on dimethenamid and dimethenamid-P2023-02-13 04:19:082023-02-17 08:30:37dmta_pathway_2022_prebuilt.rnwdmta_pathway_2022_prebuilt.pdfTesting hierarchical pathway kinetics with residue data on dimethenamid and dimethenamid-P2023-02-13 04:19:082023-02-17 13:44:29[jranke] chemCal 0.2.3.9000johannes.ranke@jrwb.de (Johannes Ranke)Simple functions for plotting linear
calibration functions and estimating standard errors for measurements
according to the Handbook of Chemometrics and Qualimetrics: Part A
by Massart et al. (1997) There are also functions estimating the limit
of detection (LOD) and limit of quantification (LOQ).
The functions work on model objects from - optionally weighted - linear
regression (lm) or robust linear regression ('rlm' from the 'MASS' package).https://github.com/r-universe/jranke/actions/runs/4239725992Fri, 01 Apr 2022 12:31:18 GMTchemCal0.2.3.9000successhttps://jranke.r-universe.devhttps://github.com/jranke/chemcalchemCal.RmdchemCal.htmlIntroduction to chemCal2018-07-05 16:44:222022-03-31 16:35:09[jranke] drfit 0.7.2jranke@uni-bremen.de (Johannes Ranke)A somewhat outdated package of basic and easy-to-use functions for
fitting dose-response curves to continuous dose-response data, calculating some
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 log-normal 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 'odbc' are included.
As an alternative to the original fitting methods, the algorithms from the 'drc'
package can be used.https://github.com/r-universe/jranke/actions/runs/4500458643Thu, 11 Oct 2018 15:00:07 GMTdrfit0.7.2successhttps://jranke.r-universe.devhttps://github.com/cran/drfit
