\title{The five-parameter growth function from Schnute and Richards (1990).}
\usage{
SchnuteRichards(t, Linf = NULL, k = NULL, a = NULL, b = NULL, c = NULL)
}
\arguments{
\item{t}{A numeric vector of ages over which to model growth.}

\item{Linf}{Mean asymptotic length.}

\item{k}{The "growth coefficient" with units of (year^(-c)).}

\item{a}{A dimensionless parameter}

\item{b}{A dimensionless parameter.}

\item{c}{A dimensionless parameter.}
}
\value{
\code{SchnuteRichards} returns a predicted size given the provided parameter values.
}
\description{
The five-parameter growth function from Schnute and Richards (1990). Note that this function is slightly modified (a \sQuote{+} was changed to a \sQuote{-} so that the \sQuote{a} parameter will be positive) from the original in Schnute and Richards (1990)
}
\section{IFAR Chapter}{
 None specifically, but 12-Individual Growth is related.
