r - 警告消息 : In file(file, "rt")

Question

这个问题已经有答案了:

'Incomplete final line' warning when trying to read a .csv file into R (17 个回答)

已关闭 10 年前。

我正在尝试将 CSV 文件导入到项目图表。我在 Mac OS X 上使用 R 2.15.2。

• 尝试的第一种方法

  我尝试运行以导入 CSV 文件的脚本是这样的:

  group4 <- read.csv("XXXX.csv", header=T)
  

  但我不断收到此错误消息:

  Error in read.table(file = file, header = header, sep = sep, quote = quote,  :   object 'XXXXXX.csv' not found 

• The second way tried

  I tried moving my working directory but got another error saying I can't move my working directory. So I went into Preferences tab and changed the working directory to the file that has my CSV files. But I still get the same error(as the first way).

• The third way tried

  Then I tried this script:

  group4 <- read.table(file.choose(), sep="\t", header=T)
  

  我收到此错误:

  Warning message: In read.table(file.choose(), sep = "\t", header = T) :  incomplete final line found by readTableHeader on '/Users/xxxxxx/Documents/Programming/R/xxxxxx/xxxxxx.csv' 

我在 R 网站和整个 Internet 上进行了搜索，但没有找到可以将这个简单的 CSV 文件导入到 R 中的方法。安慰。

Answer 1

1. 该文件不在您的工作目录中，请更改它，或使用绝对路径。
2. 您指向的目录不存在，或者您没有该目录的写入权限。
3. 文件的最后一行格式错误。
