+\name{linlogitf}
+\alias{linlogitf}
+\title{Linear-logistic function}
+\description{
+  Helper function describing a special type of dose-response curves, showing a stimulus
+  at subtoxic doses.
+}
+\usage{
+  linlogitf(x,k,f,mu,b)
+}
+\arguments{
+  \item{x}{
+    In this context, the x variable is the dose.}
+  \item{k}{
+    In the drfit functions, k is set to 1.}
+  \item{f}{
+    One of the parameters describing the curve shape.}
+  \item{mu}{
+    The parameter describing the location of the curve (log EC50).}
+  \item{b}{
+    One of the parameters describing the curve shape.}
+}
+\value{
+  The response at dose x.
+}
