如何在 R 中以逗号 (,) 作为分隔符读取 csv 文件

Question

我正在尝试在 R 中读取此 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

我试过这个：

result <- read.csv("C:/scores.csv", header = TRUE, sep = ",", quote = "\"")

和这个：

result <- read.csv("C:/scores.csv")

它不起作用，我得到 P，预测，折叠 NA 值

head(result)

但我得到了这个：

                        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

有人已经这样做了吗？

请帮忙！

Unix cat 输出如下：

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

1,0.6610699528239422,"1",0

R 输出如下：

read.csv('input.csv')
