+\begin{abstract}
+% -------------------------------------------------------------------------------
+In this vignette, we give short examples how to produce new
+distributions in packages \pkg{distr} and \pkg{distrEx}.
+This vignette refers to package version~\pkgversion.
+% -------------------------------------------------------------------------------
+\end{abstract}
+% -------------------------------------------------------------------------------
+Basically there are three ways to produce new
+distributions in packages \pkg{distr} and \pkg{distrEx}:
+\begin{enumerate}
+\item automatic generation of single distribution objects by arithmetics and the like
+\item using generating functions to produce single distribution objects
+\item defining new distribution classes / doing it from scratch
+\end{enumerate}
+We will give short examples of all three of them.
+% -------------------------------------------------------------------------------
+\section{Automatic generation by arithmetics and the like}
+% -------------------------------------------------------------------------------
+We have made available quite general arithmetical operations to our distribution
+objects, generating new image distribution objects automatically. As an example, try
+<<Prepa, echo=false, results=tex>>=
+## preparation: set option withSweave to true
+require(distr)
+distroptions(withSweave = TRUE)
+options(width=70)
+@
+%
+<<exam1, eval = TRUE, fig = TRUE>>=
+require(distr)
+N <- Norm(mean = 2, sd = 1.3)
+P <- Pois(lambda = 1.2)
+Z <- 2*N + 3 + P
+Z
+plot(Z, panel.first = grid(), lwd=2)
+p(Z)(0.4)
+q(Z)(0.3)
+Zs <- r(Z)(50)
+Zs
+@
+\par
+\noindent{\bf Comment:}\\
+Let \code{N} an object of class \code{"Norm"} with parameters \code{mean=2},
+\code{sd=1.3} and let \code{P} an object of class \code{"Pois"} with parameter
+\code{lambda=1.2}. Assigning to \code{Z} the expression \code{2*N+3+P}, a
+new distribution object is generated ---of class \code{"AbscontDistribution"} in
+our case--- so that identifying \code{N}, \code{P}, \code{Z} with random
+variables distributed according to {\tt N}, {\tt P}, {\tt Z},
+${\cal L}({\tt Z})={\cal L}(2*{\tt N}+3+{\tt P})$, and writing \code{p(Z)(0.4)}
+we get $P(Z\leq 0.4)$, \code{ q(Z)(0.3)} the $30\%$-quantile of {\tt Z},
+and with \code{r(Z)(50)} we generate $50$ pseudo random numbers distributed
+according to {\tt Z}, while the \code{plot} command generates the above figure.\\
+
+There a caveats to take care about; for details refer to the (larger) vignette
+{\tt distr} in package \pkg{distrDoc}.
+% -------------------------------------------------------------------------------
+\section{Using generating functions}
+% -------------------------------------------------------------------------------
+If you want to generate a single distribution object (without any particular parameter)
+generating functions are the method of choice:\\
+
+
+Objects of classes \code{LatticeDistribution} resp.\
+\code{DiscreteDistribution},
+\code{AbscontDistribution}, may be generated using the generating functions
+\code{LatticeDistribution()} resp.\ \code{DiscreteDistribution()}
+resp.\ \code{AbscontDistribution()}; see also
+the corresponding help.\\
+
+E.g., to produce a discrete distribution with
+support $(1,5,7,21)$ with corresponding probabilities $(0.1,0.1,0.6,0.2)$
+we may write
+<<DiscrDist, eval = TRUE, fig = TRUE>>=
+D <- DiscreteDistribution(supp = c(1,5,7,21), prob = c(0.1,0.1,0.6,0.2))
+D
+plot(D, panel.first = grid(), lwd = 2)
+@
+%
+\newline
+and to generate an absolutely continuos distribution with density proportional
+to $e^{-|x|^3}$, we write
+<<AbscDist, eval = TRUE, fig = TRUE>>=
+AC <- AbscontDistribution(d = function(x) exp(-abs(x)^3), withStand = TRUE)
+AC
+plot(AC, panel.first = grid(), lwd = 2)
+@
+%
+% -------------------------------------------------------------------------------
+\section{Doing it from scratch}
+% -------------------------------------------------------------------------------
+If you would like to create new parametric distributions, using already
+implemented {\tt r}, {\tt d}, {\tt p}, and {\tt q} functions
+(e.g.\ implementing additional distributions realized in another
+\href{http://cran.r-project.org}{\tt CRAN} package),
+you should probably envisage introducing new distribution {\tt S4} (sub-)classes
+and hence better look at the implementation of some discrete and
+continuous parametric distribution classes in package \pkg{distr}.
+
+\noindent{\small Hint: download the {\tt .tar.gz} file; extract it to some {\tt temp}
+folder; look at subdirectories {\tt R} and {\tt man}}\smallskip\\
+
+The general procedure is as follows
+
+\begin{enumerate}
+\item introduce a new subclass of class \code{Parameter}
+\item introduce a new subclass of \code{LatticeDistribution}/%
+\code{DiscreteDistribution} (if discrete)
+ or of class \code{AbscontDistribution} (if continuous).
+\item define accessor and replacement functions for the ``slots'' of the
+parameter (e.g.\ \code{"size"} and \code{"prob"} in the binomial case),
+possibly with new generics
+\item (possibly) define a validity function
+\item define a generating function
+\item if existing, define particular convolution methods or similar particular
+methods for this new distribution class
+\item create {\tt .Rd} files for the
+\begin{itemize}
+ \item parameter class
+ \item distribution class
+\end{itemize}
+\item if analytic expressions are available, define particular \code{E}-, \code{var}-,
+\code{skewness}-, and \code{kurtosis}-methods
+ and if so, also document\footnote{%
+%
+this is new, because so far, all \code{E}-, \code{var}-,
+\code{skewness}-, and \code{kurtosis}-methods for ``basic''
+distributions are documented in the \pkg{distrEx} documentation to
+\code{E}, \code{var}, \ldots, but this would not be operational
+any longer for new derived classes, possibly defined in other, new packages
+%
+ } the corresponding methods in
+ the distribution class {\tt .Rd} file\\
+\end{enumerate}
+
+Let's go through the steps in the example case of the Binomial implementation
+in packages \pkg{distr} and \pkg{distrEx}:
+
+\begin{enumerate}
+%
+\item in \pkg{distr}, see source in \file{R/AllClasses.R},
+%
+<<AllClass1, results=tex, echo=FALSE>>=
+lstinputSourceFromRForge("distr","R","AllClasses.R","distr",
+ "## Class: BinomParameter", "#-")
+@
+%
+\item in \pkg{distr}, see source in \file{R/AllClasses.R},
+%
+<<AllClass2, results=tex, echo=FALSE>>=
+lstinputSourceFromRForge("distr","R","AllClasses.R","distr",
+ from = "## Class: binomial distribution",
+ to = "contains = \"LatticeDistribution\"",
+ offset.after = 1)
+@
+%
+\item in \pkg{distr}, see source in \file{R/BinomialDistribution.R},
+%
+<<BinomDist1, results=tex, echo=FALSE>>=
+lstinputSourceFromRForge("distr","R","BinomialDistribution.R","distr",
+ from = c("## Access Methods", "## wrapped access methods"),
+ to = c("setReplaceMethod\\(\"prob\", \"BinomParameter\"",
+ "size = value\\)\\)") ,
+ offset.after = c(1,1))
+@
+%
+and \file{R/AllGenerics},
+<<AllGenerics, results=tex, echo=FALSE>>=
+lstinputSourceFromRForge("distr","R","AllGenerics.R","distr",
+ from = "if\\(!isGeneric\\(\"size\"",
+ to = "setGeneric\\(\"prob\"")
+@
+%
+\item in \pkg{distr}, see source in \file{R/BinomialDistribution.R},
+%
+<<BinomDist2, results=tex, echo=FALSE>>=
+lstinputSourceFromRForge("distr","R","BinomialDistribution.R","distr",
+ from = "setValidity\\(\"Binom",
+ to = "else return\\(TRUE\\)",
+ offset.after = 1)
+@
+%
+\item in \pkg{distr}, see source in \file{R/BinomialDistribution.R},
+%
+<<BinomDist3, results=tex, echo=FALSE>>=
+lstinputSourceFromRForge("distr","R","BinomialDistribution.R","distr",
+ from = "Binom <- function",
+ to = "Binom <- function")
+@
+%
+\item in \pkg{distr}, see source in \file{R/BinomialDistribution.R},
+%
+<<BinomDist4, results=tex, echo=FALSE>>=
+lstinputSourceFromRForge("distr","R","BinomialDistribution.R","distr",
+ from = "## Convolution for",
+ to = "\\}\\)")
+@
+%
+\item in \pkg{distr}, see sources in
+%
+\begin{itemize}
+%
+\item\file{man/BinomParameter-class.Rd}
+%
+<<BinomParam, results=tex, echo=FALSE>>=
+lstinputSourceFromRForge("distr","man","BinomParameter-class.Rd","distr")
+@
+%
+\item\file{man/Binom-class.Rd}
+<<Binomclass, results=tex, echo=FALSE>>=
+lstinputSourceFromRForge("distr","man","Binom-class.Rd","distr")
+@
+%
+\item {\footnotesize you could have: \file{man/Binom.Rd}
+ for the generating function; in the Binomial case, documentation is in
+ \file{Binom-class.Rd}; but in case of the Gumbel distribution,
+ in package \pkg{distrEx}, there is such an extra {\tt .Rd} file}
+%
+\end{itemize}
+%
+\item in \pkg{distrEx}, see sources in
+%
+<<Prepa2, echo=false, results=tex>>=
+## preparation: set option withSweave to true
+require(distrEx)
+@
+%
+\begin{itemize}
+%
+\item\file{Expectation.R},
+<<Expect, results=tex, echo=FALSE>>=
+lstinputSourceFromRForge("distrEx","R","Expectation.R","distr",
+ from = "\"E\", signature\\(object = \"Binom\"",
+ to = "\\}\\)")
+@
+%
+\item\file{Functionals.R},
+<<var, results=tex, echo=FALSE>>=
+lstinputSourceFromRForge("distrEx","R","Functionals.R","distr",
+ from = "\"var\", signature\\(x = \"Binom\"",
+ to = "\\}\\)")
+@
+%
+\item\file{skewness.R},
+<<skew, results=tex, echo=FALSE>>=
+lstinputSourceFromRForge("distrEx","R","Skewness.R","distr",
+ from = "\"skewness\", signature\\(x = \"Binom\"",
+ to = "\\}\\)")
+@
+%
+\item\file{kurtosis.R},
+<<kurt, results=tex, echo=FALSE>>=
+lstinputSourceFromRForge("distrEx","R","Kurtosis.R","distr",
+ from = "\"kurtosis\", signature\\(x = \"Binom\"",
+ to = "\\}\\)")
+@
+%
+\end{itemize}
+\end{enumerate}
+The procedure will be similar for \textit{any} new class of distributions.\medskip
+\begin{itemize}
+ \item[Comment] In the classes in package \pkg{distr} (historically the ``oldest''
+ in the development of this project), we still use \code{initialize} methods;
+ this is no longer needed, if you provide generating functions; for this ``more
+ recent'' approach, confer the realization of class \code{Gumbel} in package \pkg{distrEx}.
+\end{itemize}
