write.table()，是保存數(shù)據(jù)為文件的函數(shù)。

> xiaohuqingdan <- c(3900088702, 3900072499,3900021029)
> xiaohuqingdan
[1] 3900088702 3900072499 3900021029
> write.table(xiaohuqingdan,"1234.txt")

得到的1234.txt，打開是這個(gè)樣子：

"x"
"1" 3900088702
"2" 3900072499
"3" 3900021029

"x"是列名，"1","2","3"是行名。不輸出列名、行名和代表字符串的雙引號(hào)——加參數(shù)：quote = FALSE,row.names = FALSE, col.names = FALSE。

> write.table(xiaohuqingdan,"4321.txt",quote = FALSE,row.names = FALSE,
              col.names = FALSE)

再次得到的4321.txt，打開來就成了這樣：

3900088702
3900072499
3900021029
