用双引号读取R中的csv文件

Question

假设我有一个csv文件,如下所示:

Type,ID,NAME,CONTENT,RESPONSE,GRADE,SOURCE
A,3,"","I have comma, ha!",I have open double quotes",A,""

期望的输出应该是:

df <- data.frame(Type='A',ID=3, NAME=NA, CONTENT='I have comma, ha!',
                 RESPONSE='I have open double quotes\"', GRADE=A, SOURCE=NA)
df
  Type ID NAME           CONTENT                   RESPONSE GRADE SOURCE
1    A  3   NA I have comma, ha! I have open double quotes"     A     NA

我尝试使用read.csv,因为数据提供程序使用quote来转义字符串中的逗号,但是他们忘记了在没有逗号的字符串中转义双引号,所以无论我是否禁用引用,read.csv我都不会获得所需的输出.

我怎么能在R中这样做？其他包装解决方案也欢迎.

Answer 1

fread从data.table处理此就好了:

library(data.table)

fread('Type,ID,NAME,CONTENT,RESPONSE,GRADE,SOURCE
A,3,"","I have comma, ha!",I have open double quotes",A,""')
#   Type ID NAME           CONTENT                   RESPONSE GRADE SOURCE
#1:    A  3      I have comma, ha! I have open double quotes"     A
