<div class="section-title">R package + Prediction Engine <em>runtime</em>.</div>
In R you install two things: the **rbpengine** package, and the Prediction Engine runtime from Cambridge Sports Analytics. The package alone is not enough to run predictions — the runtime and a [[License Key|license key]] are required.
<p> </p>
## What you need
- R 4.1 or newer
- The **rbpengine** package (from CSA or the channel they specify)
- The Prediction Engine runtime installer for your Mac, Linux, or Windows machine
- A license from CSA
## 1. Install the R package
Follow the install instructions CSA gives you for **rbpengine** (for example an install file or package repository link).
Then in R:
```r
library(rbpengine)
engine_available()
```
If the runtime is not installed yet, <span class="mono">engine_available()</span> returns <span class="mono">FALSE</span>. That is expected until step 2 is done.
## 2. Install the Prediction Engine runtime
Use the installer or package CSA sent for your platform. Details: [[Install/Native Runtime|Desktop or server installer]].
After install, the engine is usually found automatically. If R still cannot see it, CSA’s installer notes explain how to point your session at the install location.
## 3. Activate your license
With the runtime installed, continue to [[License Key]].
```bash
rbp-license-info
rbp-license-info --setlicense RBP-LIC-1:…
```
## Check that you are ready
```r
library(rbpengine)
engine_available() # should be TRUE after the runtime is installed
```
