チャンクオプションをローカルに設定する
レポートを作成するとき、最終レポートでの図の表示を変えたい場合は、チャンクオプションをローカルに設定することがあります。investment_annual_summary データは有益な背景情報を提供しますが、このレポートの焦点はブラジルのプロジェクトです。この演習では、ブラジルのプロジェクトに関する情報を表示するプロットが、投資年次サマリーデータの概要プロットより少し大きく表示されるように、チャンクオプションをローカルに変更します。

R Markdown でレポート作成
演習の手順
investment-annual-summaryチャンクに追記し、生成される図の出力サイズを 85% にします。brazil-investment-projectsとbrazil-investment-projects-2018の各チャンクに追記し、図の出力サイズを 95% にします。
