Question

我有一个超过60,000行的文本文件，我需要阅读。我使用了fread函数，我的代码如下。（示例如下所示的两行）。我需要一个输出，如“输出”表中所示。

有人可以帮助我获得我想要的输出。任何帮助表示赞赏。

library(data.table)
file1 <- 'sample.txt'
data <- fread(file1)

Error:

Error in fread(in_file1) : 
  Expecting 13 cols, but line 20 contains text after processing all cols. Try again with fill=TRUE. Another reason could be that fread's logic in distinguishing one or more fields having embedded sep=' ' and/or (unescaped) '\n' characters within unbalanced unescaped quotes has failed. If quote='' doesn't help, please file an issue to figure out if the logic could be improved.
