我正在读一个csv文件.

代码是:

mydata = read.csv("mycsv.csv", header=True, sep=",", quote="\"")

获取以下警告:

警告消息:In scan(file = file, what = what, sep = sep, quote = quote, dec = dec,:在输入中找到的嵌入式nul(s)

现在我的CSV中的一些单元格缺少由""表示的值.

如何编写此代码以便我不会收到上述警告？

我一直在尝试阅读excel文件但看起来有些不对劲.该文件以excel格式存储在Documents文件夹中.

这些是我得到的错误消息:

table <- read.csv(file.choose(),header=T,sep='\t')

Warning messages:
1: In read.table(file = file, header = header, sep = sep, quote = quote,  :
  line 1 appears to contain embedded nulls
2: In read.table(file = file, header = header, sep = sep, quote = quote,  :
  incomplete final line found by readTableHeader on 

此外,由于这些是警告,我碰巧忽略了它们.但是没有任何东西被读入"表格":

table
# [1] PK...
# <0 rows> (or 0-length row.names)
