The rcbc package provides an interface to the CBC (COIN-OR branch and cut) solver. Specifically, CBC is an open-source mixed integer programming solver that is developed as part of the Computational Infrastructure for Operations Research (COIN-OR) project. By interfacing with the CBC solver, the rcbc package can be used to generate optimal solutions to optimization problems. Please note that this package is under active development and is still a work in progress.


The package is not yet available on The Comprehensive R Archive Network. To install this package, please use the following R code to install it from the source code repository on GitHub. Please note that CBC solver header and library files also need be installed prior to installing this R package (see below for details).

if (!require(remotes))


The package can be installed from source when the Rtools software is installed. Specifically, the CBC solver header and library files are automatically downloaded from RWinLib.



The following system command can be used install dependences.

sudo apt-get install coinor-libcbc-dev coinor-libclp-dev


The following system command can be used install dependences.

sudo yum install coin-or-Cbc-devel coin-or-Clp-devel


The following system command can be used install dependences using Homebrew package manager.

brew install coin-or-tools/coinor/cbc


Here we will provide a brief example showing how the package can be used to solve an optimization problem (see package vignette for more details).

# load package

# define optimization problem and solve it
## max 1 * x + 2 * y
## s.t.
##   x + y <= 1
##   x, y binary
result <- cbc_solve(
 obj = c(1, 2),
 mat = matrix(c(1, 1), ncol = 2, nrow = 1),
 is_integer = c(TRUE, TRUE),
 row_lb = -Inf, row_ub = 1, max = TRUE,
 col_lb = c(0, 0), col_ub = c(1, 1),
 cbc_args = list("SEC" = "1"))

# extract solution status
#> [1] "optimal"

# extract solution values
#> [1] 0 1

# extract objective value for solution
#> [1] 2

ROI plugin

There is now a work in progress ROI plugin.
