r - R fread 输入返回 0 行

Question

我无法理解我的 fread 进口出了什么问题。当我使用具有相同参数的 read.csv 时，数据正在正确读取，但我无法使用它，因为其他文件无法使用它。

    ths<-read.csv(path_data, sep = ",",header = TRUE,stringsAsFactors = FALSE)
    df <- data.table::fread(file=path_data,
        header = TRUE,
        sep = ",",quote = '',stringsAsFactors = FALSE)
      

我不能给你文件所以这里是一个数据样本：
