您好,我正在尝试读取一个 csv 文件,我想要一个向量文件内部如

head filetoread.csv 
0610010K14Rik,0610011F06Rik,1110032F04Rik,1110034G24Rik,1500011B03Rik,1700019L03Rik,1700021K19Rik, blah,blah,...

在 R session 中:

c <- read.csv("filetoread.csv")
> c
[1] X0610010K14Rik X0610011F06Rik X1110032F04Rik
...
> str(c)
'data.frame': 0 obs. of 2840 variables:
$ X0610010K14Rik : logi
$ X0610011F06Rik : logi
$ X1110032F04Rik : logi
$ X1110034G24Rik : logi
...

但我想要这样的东西:

> c
[1] "X0610010K14Rik" "X0610011F06Rik" "X1110032F04Rik" ...
str(c)
chr [1:2840] "X0610010K14Rik" "X0610011F06Rik" "X1110032F04Rik"...

最佳答案

我们可以使用扫描

scan("filetoread.csv", sep=',', what = "", quiet = TRUE)
#[1] "0610010K14Rik" "0610011F06Rik" "1110032F04Rik" "1110034G24Rik"
#[5] "1500011B03Rik" "1700019L03Rik" "1700021K19Rik" " blah" "blah"
