使用参数创建新报告
现在您已在文档中加入参数,接下来请使用 country 参数,基于 investment_services_projects 数据为 Bangladesh 创建一份新报告。
在编织报告之前,请先检查并修改文档中的文字,确保编织后的报告能够反映参数中指定的国家。
本练习是课程的一部分
使用 R Markdown 生成报告
练习说明
- 将文档页眉中的
Brazil替换为对country参数的引用。 - 在 YAML 头部的
"Investment Report"标题字段中加入country参数,这样在文件编织后,报告标题会呈现为 "Investment Report for Projects in Bangladesh"。 - 使用
country参数,为 Bangladesh 创建一份新的 Investment Report 文件。
