试图读入“|”使用data.table包中的fread（）分隔文件并收到错误。错误是“'在第104970行结束字段14”。
有没有看到更老的问题，询问fread（）是否有报价处理功能，还没有找到最新的东西。还注意到“sep2”功能即将推出，这是解决这个长期问题的功能吗？
我可以使用read.table（）读取相同的数据：
df.readtable<-read.table(myfile,header=F,sep="|",quote="\"",fill=T,stringsAsFactors=F)
但是我无法使用fread（）重现结果：
> require(data.table)
> df.fread<-fread(myfile,verbose=T)

First row with 17 fields occurs on line 1 (either column names or first row of data)
Some fields on line 1 are not type character (or are empty). Treating as a data row and using default column names.
