R语言，read in scan 报错。

R语言中读写文件时报错

** 没有报错的情况**

> write.table(iris,file = "E:/study/RData/newfile.csv",sep=",")
> read.table("E:/study/RData/newfile.csv")

报错的情况

write.table(iris,file = "E:/study/RData/newfile1.csv",sep = ",",row.names=F)
> read.table("E:/study/RData/newfile1.csv")
Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec,  : 
  line 2 did not have 2 elements

多加了一个row.names=F，就出现如上报错，怎么解决？

没有正确理解
