我能'；t将我的yaml文件加载到R中

最后，我想在ahp包中使用我的yaml文件。但首先，我需要将我的yaml文件读入R。我用Notepad++创建了我的文件，并且所有内容都是选项卡描述的

我使用以下代码尝试在R中读取我的文件：

GIC <- yaml.load_file("/filepath/filename.yml") 

---

“不完整的最后一行”：您需要在文件末尾换行；尽管如此，由于第46行（您应该将其重命名/移到别处），您将有一个“Duplicate map key:‘children’”，YAML文档的可能副本清楚地说明了为什么要忽略这一点并使用tab deliniation？请注意，YAML不需要在文件末尾换行，如果R的实现需要，这是一个bug，应该报告。
