我想在Rmd中读取一个txt
--- title: "Untitled" output: html_document --- ```{r} country <- read.table("country.txt") country ```
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:... withCallingHandlers -> withVisible -> eval -> eval -> read.table - > file Execution halted
但我可以成功地在R控制台中运行代码

该文件存在于wd中
> file.exists("country.txt") [1] TRUE
我也尝试使用read.csv()但它显示类似的错误:
processing file: Preview-28786aad2e0.Rmd Quitting from lines 6-8 (Preview-28786aad2e0.Rmd) Error in file(file, "rt") : cannot open the connection Calls:... withVisible -> eval -> eval -> read.csv -> read.table -> file Execution halted

简短的回答是:
知道吗
getwd()
不要将当前R控制台的工作目录与R Markdown文档的工作目录(此R Markdown文档的目录)混淆.如有疑问,请打印出getwd()
您想知道工作目录的位置(例如*.Rmd).注意R Markdown文档在单独的R会话中编译以提高可重复性,因此您当前的R控制台与R Markdown文档的编译无关.
