• ArcGIS 10.3.1 or ArcGIS Pro 1.1 (don't have it? try a 60 day trial)
• R Statistical Computing Software, 3.1.0 or later (What is R?)

• 32-bit version required for ArcMap, 64-bit version required for ArcGIS Pro (Note: the installer installs both by default).
• 64-bit version can be used with ArcMap by installing Background Geoprocessing and configuring scripts to run in the background.

####Installation

For most users, the easiest way to install is using the installation toolbox which will install and configure the bridge for ArcGIS 10.3.1+ and Pro 1.1+. Alternatively, downloading the release can be manually installed into R, as shown in this screencast.

####Basic GP Tool script

tool_exec <- function (in_params, out_params)
{
  value0 <- in_params[[1]]
  print(value0)
# ...
  return (out_params)
}

• tool_exec(in_params, out_params) main function

• in_params list of all input parameters. You can get parameter value by index in_params[[1]] or by parameter name in_params$param1
• output_params list of all output and derived parameters.

####Using arcgisbinding in standalone R script

> library(arcgisbinding)
> arc.check_product()

####Building from source

• Create new folder <ArcGIS>\R-bridge
• Set as current directory and clone repository
  git clone https://github.com/R-ArcGIS/r-bridge.git ./src
• Open R-bridge.sln (Visual Studio 2012) and build solution

######Build dependencies:

• ArcObjects SDK for C++ 10.3.1 (requirements)
• Rtools 3.1 or 3.2

######Documentation dependencies:

• roxygen2, install from R: install.packages('roxygen2')
• MiKTeX 2.9, to build package PDF

###Repository layout

• .\package
  arcgisbinding (native R package) - collection of classes and functions for script-level bindings between R and bridge dll.
• .\rarcproxy
  C++, Bridge between ArcGIS 10.3.1 and arcgisbinding.
• .\rarcproxy_pro
  C++, Bridge between ArcGIS Pro and arcgisbinding.
• .\libarcobjects
  (private) - Static library for rarcproxy_pro. Wrapper classes for ArcObjects API.
