我使用read.table函数读入一个用tab分割的txt数据文件出现了下面的警告信息:
Warning messages:
1: In scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, :
EOF within quoted string
2: In scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, :
number of items read is not a multiple of the number of columns
请问这是什么原因造成的?
