我有一个.txt数据集，其中所述第一12行文本接着用2个空行，然后将数据fread为什么不接受skip命令？

DATE   HEIGHT INPUT  OUTPUT TESTMEASURE 
01/01/1933 NO RECORD NO RECORD MISSING  MISSING 
01/02/1933 NO RECORD NO RECORD MISSING  MISSING

但是，当我做

dat <- fread('data.txt'),

它将跳过15行，和用途第一条数据行作为导入数据集的列名称。它忽略标题行。

01/01/1933 NO RECORD NO RECORD MISSING  MISSING

跳跃参数没有影响我在导入所有。我如何提到需要用作列名的行号？或者我可以重命名列名，但不应该忽略第一行数据。

诊断

Input contains no \n. Taking this to be a filename to open 
File opened, filesize is 0.001319 GB. 
Memory mapping ... ok 
Detected eol as \r\n (CRLF) in that order, the Windows standard. 
Positioned on line 1 after skip or autostart 
This line is the autostart and not blank so searching up for the last non-blank ... line 1 
Detecting sep ... '\t' 
Detected 5 columns. Longest stretch was from line 15 to line 30 
Starting data input on line 15 (either column names or first row of data). First 10 characters: 01/01/1933 
The line before starting line 15 is non-empty and will be ignored (it has too few or too many items to be column names or data): DATE   HEIGHT INPUT OUTPUT TESTMEASURE the fields on line 15 are character fields. Treating as the column names.

它应该是'dat < - fread（'data.txt'，skip = 15）'？ – CPak

@ChiPak我需要跳过12 + 2 = 14行。但是，下面的任何内容，15，和数据集不受影响。 – maximusdooku

无论我跳过什么，导入的第一行都是01/02/1933。 – maximusdooku

你有12行文字，2号线的空间，然后你的数据。但是我注意到DATE和HEIGHT之间有额外的空白。所以作出这样，你的数据是制表符分隔的文本文件，并添加2标签DATE和HEIGHT代替fread(data)之间1片

DATE  HEIGHT INPUT OUTPUT TESTMEASURE 
01/01/1933 NO RECORD NO RECORD MISSING MISSING 
01/02/1933 NO RECORD NO RECORD MISSING MISSING

做给我：

fread(data) 
    01/01/1933 NO RECORD NO RECORD MISSING MISSING 
1: 01/02/1933 NO RECORD NO RECORD MISSING MISSING

删除DATE和HEIGHT之间的额外选项卡给我：

  DATE HEIGHT  INPUT OUTPUT TESTMEASURE 
1: 01/01/1933 NO RECORD NO RECORD MISSING  MISSING 
2: 01/02/1933 NO RECORD NO RECORD MISSING  MISSING
