如何在R中以逗號（，）作為分隔符讀取csv文件

Question

我正在嘗試在R中讀取此csv文件（scores.csv）

ALVO,P,Prediction,fold
1,0.9079557994069131,"1",0
1,0.4323657303144317,"0",0
1,0.9944246408740756,"1",0
1,0.8025072441292207,"1",0
1,0.8687043760021418,"1",0
1,0.8728815023271057,"1",0
1,0.9998157504312343,"1",0
1,0.6610699528239422,"1",0
1,0.9994385364719802,"1",0

我已經試過了：

結果<-read.csv（“ C：/scores.csv”，標頭= TRUE，sep =“，”，引號=“ \\”“）

和這個：

結果<-read.csv（“ C：/scores.csv”）

它不起作用，我得到P，Prediction和NA值的倍數

頭（結果）

但是我得到了：

                        ALVO  P Prediction fold
1 1,0.9079557994069131,"1",0 NA         NA   NA
2 1,0.4323657303144317,"0",0 NA         NA   NA
3 1,0.9944246408740756,"1",0 NA         NA   NA
4 1,0.8025072441292207,"1",0 NA         NA   NA
5 1,0.8687043760021418,"1",0 NA         NA   NA
6 1,0.8728815023271057,"1",0 NA         NA   NA

已經有人做過嗎？

請幫忙！

Unix cat輸出如下：

> cat input.csv 
ALVO,P,Prediction,fold
1,0.9079557994069131,"1",0
1,0.4323657303144317,"0",0

R輸出如下：

read.csv('input.csv')
