启动RStudio并尝试从.rnw格式编译PDF时出现以下问题:
Error: '\U' used without hex digits in character string starting ""C:\U"
当启动RStudio或仅启动R时，这就是控制台内的内容:

Global .Rprofile loaded!
Error: '\U' used without hex digits in character string starting ""C:\U"
当我尝试编译PDF时会发生这种情况:
Global .Rprofile loaded!
Error: '\U' used without hex digits in character string starting ""C:\U"
Execution halted
这种情况从一天到一天都在出现，我不确定发生了什么变化。我尝试更新RStudio和我的R版本，但没有帮助。我在Windows上运行R。
有人可以帮我解决这个问题吗？
最佳答案
我毕竟能够解决这个问题:
我的.Rprofile文件(在“文档”中)有一个部分，其中用“\”而不是“/”。
所以我现在改变了
# Set mainfolder for PACKAGE package
options(PACKAGE_MAINFOLDER="C:\Users\...")
至
# Set mainfolder for PACKAGE package
options(PACKAGE_MAINFOLDER="C:/Users/...")
这就是窍门。
