Introduction

This manual is designed for GTAP users.
For a comprehensive guide, please refer to the GTAPViz Vignette.

This document requires the following R scripts, aligned with the navigation menu:

  • 1.ProjectSetup.R — 1. Project Setup
  • 2.PlotGens.R — 2. Plotting
  • 3.TableGens.R — 3. Table

If you do not have these R script files (located in the GTAPViz-user folder), please download the ZIP file:
