Getting Started

Once you have been welcomed to VisionEval, you can follow the instructions under “Running VE Models” on the Getting Started page. Your destination folder contains everything you need from the VisionEval “sources” folder.

The installation also creates some convenience functions which will run the model test scenarios or start the VE GUI:

• vegui() to start the GUI (navigate to your destination folder to find the scenario run scripts)
• verpat() for the VERPAT test model
• verpat(scenarios=TRUE) to run multiple scenarios in VERPAT
• verpat(baseyear=TRUE) to run the alternate VERPAT sample scenario
• verspm() for the VERSPM test model
• verspm(scenarios=TRUE) to run multiple scenarios in VERSPM

Requirements

If the above installation steps did not succeed, ensure that you have downloaded the appropriate version of VisionEval to match the version of R that you have installed.

R

The current version of VisionEval works best with R 3.5.2 to be installed on your computer. If you currently have another version of R installed, you can go to the GitHub release page to download VisionEval for R 3.4.4 or 3.5.1.

You can find the R 3.5.2 installer for Windows here.

RStudio (optional)

Many users find that RStudio is a better version of the standard R interface. RStudio is particularly recommended if you plan to clone and explore the Visioneval source code from GitHub.

Mac/Linux users

VisionEval can be installed from source as well. Follow the ‘Install from Source’ steps on the wiki.
