通过简单地尝试使用 read.table 和 header=T, dec=".", sep="" 作为附加参数，我收到此错误：

Error in read.table("C:\\blablabla\\file.txt)
  more columns than column names
Execution halted

我认为该文件不是 \t 而是分开 "". 。我还认为这可能是由表格前的额外文本引起的。会 read.csv 做出改变？

有什么建议么？提前致谢。

Answer 1

问题在于列名称上方列出了一些附加信息。只需跳过此步骤即可解决您的问题。为此，您可以使用 skip 参数是 read.csv.

dat = read.csv('/path/to/file.csv', header = TRUE, dev = ".", sep = "", skip = 9)
