我想在Rmd中阅读txt
---
title: "Untitled"
output: html_document
---
```{r}country <- read.table("country.txt")
国家/地区
它显示错误：
processing file: Preview-2878539db5c7.Rmd
Quitting from lines 6-8 (Preview-2878539db5c7.Rmd)
Error in file(file, "rt") : cannot open the connection
Calls: <Anonymous> ... withCallingHandlers -> withVisible -> eval -> eval -> read.table - > file
Execution halted但是我可以在R控制台中成功地运行代码
> country <- read.table("country.txt")
> country
