Question

我试图在R中读取.csv。一列中的某些行的文本带有komma，在双引号内：＆＃34;例如，另一个示例＆＃34; 但是当我尝试这样读它时，R改变了行（它增加了行数）：

steekproef <- read.csv('steekproef.csv', header = T, quote = "", sep = ',')

当我在互联网上搜索时，这个不起作用：

steekproef <- read.csv('steekproef.csv', header = T, quote = "\"", sep = ',')

这是错误消息：

steekproef <- read.csv("steekproef.csv", header = T, sep =",", quote ="\"")

comes with error:

Warning message:
In scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings,  :
EOF within quoted string

Gives data.frame:      1391160 obs. of  29 variables


str(steekproef) gives no error but a

'data.frame':  3103620 obs. of  29 variables:


The dataset has 29 columns and 3019438 rows

Answer 1

我不认为问题是由“另一个例子”引起的：

我在Excel中创建了一个测试文件并将其保存为.csv。在Notepad ++中看起来像这样：

test,num
"example, another example",1
"example, another example",2
example,3
example,4

我可以使用

毫无问题地导入它

steekproef<- read.csv('steekproef.csv', header = T, sep = ',')

或steekproef <- read.csv('steekproef.csv', header = T, quote = "\"", sep = ',')

您的第一次尝试：steekproef <- read.csv('steekproef.csv', header = T, quote = "", sep = ',')给了我Error in read.table(file = file, header = header, sep = sep, quote = quote,: duplicate 'row.names' are not allowed

R - read.csv在加载数据集时添加行
