-\section{Introduction}
-The package \pkgname{} provides a low level interface to the C~API of
-COIN-OR Clp\footnote{COIN-OR linear programming version 1.12.0 or higher
-\url{https://projects.coin-or.org/Clp}} (COIN-OR linear programming).
-The package \pkgname{} relies on a separate installation of COIN-OR Clp.
-
-\section{Installation}
-See \Comp{INSTALL} for installation instructions and platform specific details.
-
-\section{Usage}
-
-In the following, an example lp-problem will be created and solved:
-
-\noindent
-\hspace{.5in} maximize
-$$z = 5 x_1 + 4 x_2 + 3 x_3$$
-\hspace{.5in} subject to
-$$
-\begin{array}{r@{\:}c@{\:}r@{\:}c@{\:}r@{\:}c@{\:}r}
-2 x_1 &+& 3 x_2 &+& x_3 & \leq 5 \\
-4 x_1 &+& x_2 &+& 2 x_3 & \leq 11 \\
-3 x_1 &+& 4 x_2 &+& 2 x_3 & \leq 8 \\
-\end{array}
-$$
-\hspace{.5in} where all variables are non-negative
-$$x_1 \geq 0, \ x_2 \geq 0, \ x_3 \geq 0$$
-
-\noindent
-Load the library.
-<<>>=
-library(clpAPI)
-@
-Create a problem object.
-<<>>=
-prob <- initProbCLP()
-@
-Set the direction of optimization ($-1$: maximize, $1$: minimize).
-<<>>=
-setObjDirCLP(prob, -1)
-@
-Prepare data structures for the problem object. Number of columns and rows:
-<<>>=
-nc <- 3
-nr <- 3
-@
-The constraint matrix is passed in column major order format. \textbf{Be
-careful here:} all indices start with 0! Row indices.
-<<>>=
-ia <- c(0, 1, 2, 0, 1, 2, 0, 1, 2)
-@
-Column indices.
-<<>>=
-ja <- c(0, 3, 6, 9)
-@
-Non-zero elements.
-<<>>=
-ar <- c(2, 4, 3, 3, 1, 4, 1, 2, 2)
-@
-Lower bounds for the variables (columns).
-<<>>=
-clb <- rep(0, 3)
-@
-Right hand side (row upper bounds for the rows).
-<<>>=
-rub <- c(5, 11, 8)
-@
-Objective coefficients.
-<<>>=
-obj <- c(5, 4, 3)
-@
-Load problem data into the problem object.
-<<>>=
-loadProblemCLP(prob, nc, nr, ia, ja, ar, clb, NULL, obj, NULL, rub)
-@
-Solve the problem using the simplex algorithm.
-<<>>=
-solveInitialCLP(prob)
-@
-Retrieve the value of the objective function after optimization.
-<<>>=
-getObjValCLP(prob)
-@
-Retrieve the primal values of the structural variables (columns) after
-optimization.
-<<>>=
-getColPrimCLP(prob)
-@
-Retrieve the dual values of the structural variables (columns) after
-optimization (reduced costs).
-<<>>=
-getColDualCLP(prob)
-@
-Free memory, allacated to the problem object.
-<<>>=
-delProbCLP(prob)
-@
-
-
-\section{Function names}
-
-\subsection{Searching}
-
-The function names in \pkgname{} are different from the names in
-\prgname{COIN-OR Clp},
-e.\,g. the function \texttt{addColsCLP} in \pkgname{} is called
-\texttt{Clp\_addColumns} in \prgname{COIN-OR Clp}. The directory \texttt{inst/}
-containes a file \texttt{c2r.map} which maps a \prgname{COIN-OR Clp} function
-name to the corresponding \pkgname{} function name. Additionally, all man-pages
-contain an alias to the \prgname{COIN-OR Clp} function name. The call
-<<>>=
-help("Clp_addColumns")
-@
-will bring up the man-page of \texttt{addColsCLP}.
-
-
-\subsection{Mapping}
-
-The file \texttt{c2r.map} in \texttt{inst/} maps the \pkgname{} function names
-to the orininal \prgname{COIN-OR Clp} function names of its C-API.
-To use the latter, run
-<<>>=
-c2r <- system.file(package = "clpAPI", "c2r.map")
-source(c2r)
-@
-now either
-<<>>=
-pr1 <- initProbCLP()
-delProbCLP(pr1)
-@
-or the original functions
-<<>>=
-pr2 <- Clp_newModel()
-Clp_deleteModel(pr2)
-@
-work both. Keep in mind that the mapping only affects the function names not the
-arguments of a function.
