From 4d60b8ed0236af9227db79bf062f2381e683cc4a Mon Sep 17 00:00:00 2001 From: ranke Date: Mon, 22 May 2006 18:59:14 +0000 Subject: Make the logit model work again, by setting a sensible starting value for the scale argument. Now all models get separate starting arguments, with hopefully effective default values. git-svn-id: http://kriemhild.uft.uni-bremen.de/svn/drfit@80 d1b72e20-2ee0-0310-a1c4-ad5adbbefcdc --- man/drfit-package.Rd | 6 ++++-- man/drfit.Rd | 18 ++++++++++++------ 2 files changed, 16 insertions(+), 8 deletions(-) (limited to 'man') diff --git a/man/drfit-package.Rd b/man/drfit-package.Rd index 43334ff..3064787 100644 --- a/man/drfit-package.Rd +++ b/man/drfit-package.Rd @@ -8,7 +8,9 @@ Dose-response data evaluation See \url{../DESCRIPTION} } \details{ -There is a preliminary version of an introductory article located in \url{../doc/drfit-Rnews.pdf}. +There is an introductory article located in \url{../doc/drfit-Rnews.pdf}, +which will be published in the R News special edition on the use +of R for chemists. } \author{ Author and Maintainer: Johannes Ranke @@ -28,5 +30,5 @@ the advantage of my package is its user-friendliness. data(antifoul) r <- drfit(antifoul) format(r,digits=2) -\dontrun{drplot(r,antifoul,overlay=TRUE,bw=FALSE)} +drplot(r,antifoul,overlay=TRUE,bw=FALSE) } diff --git a/man/drfit.Rd b/man/drfit.Rd index 453c0f8..6b98f36 100644 --- a/man/drfit.Rd +++ b/man/drfit.Rd @@ -8,7 +8,7 @@ \usage{ drfit(data, startlogED50 = NA, chooseone = TRUE, probit = TRUE, logit = FALSE, weibull = FALSE, linlogit = FALSE, level = 0.95, linlogitWrong = NA, - allWrong = NA, s0 = 0.5, b0 = 2, f0 = 0) + allWrong = NA, ps0 = 1, ls0 = 0.5, ws0 = 0.5, b0 = 2, f0 = 0) } \arguments{ \item{data}{ @@ -56,12 +56,18 @@ logit, weibull, and the first model that produces a valid fit is used.
