r语言读取csv数据 r语言读取csv数据的第二列

在R语言中使用read.table()读入CSV文件的数据。

1、假定有score.csv文件

ID,score1,score2,Gender
 101,11.35321,0.2,male
 102,12.58654,0.6,male
 103,19.7938,0.9,female
 104,12.01352,0.4,female
 105,11.97081,0.4,female
 106,17.3748,0.7,female
 107,14.24884,0.3,female
 108,18.47972,0.8,male
 109,18.74792,0.8,male
 110,18.90146,0.7,male

2、第一行为标题，其他各行为数据，读入到R工作空间中

> score<-read.table("E:\\Work\\lunwen\\score.csv",header=TRUE,sep=',')

3、检查是否导入正常

> score
     ID   score1 score2 Gender
 1  101 11.35321    0.2   male
 2  102 12.58654    0.6   male
 3  103 19.79380    0.9 female
 4  104 12.01352    0.4 female
 5  105 11.97081    0.4 female
 6  106 17.37480    0.7 female
 7  107 14.24884    0.3 female
 8  108 18.47972    0.8   male
 9  109 18.74792    0.8   male
 10 110 18.90146    0.7   male
