r - read.table 并删除最后几行 (R)

Question

我正在尝试将文本文件中的内容转换为 R 中的数据框。我想跳过前三行，然后*End使用 read.table 只读取到上面的行，如下所示：

df <- read.table("file.txt", sep = ",", dec = ".", skip = 3, nrows = length("file.txt")-2)

但我收到此错误：

Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec,  : 
line 8 did not have 4 elements

数据如下所示：

*End
