我有一个 csv 文件，我使用 read.csv 将其加载到 R 中并执行了一些操作。而且，现在我需要将其写回 csv 格式。然而问题是， write.table() 函数不会产生所需的输出。

初始数据：

id,name,Households,Population,Total Male,Total Female
0,Nepal,5427302,26494504,12849041,13645463
1,Taplejung,26509,127461,60552,66909
2,Panchthar,41196,191817,90186,101631
3,Ilam,64502,290254,141126,149128
4,Jhapa,184552,812650,385096,427554

使用 write.table() 的最终输出

"id","name","Households","Population","SexRatio"
"1",0,"Nepal",5427302,26494504,94.1634666408901
"2",1,"Taplejung",26509,127461,90.499036004125
"3",2,"Panchthar",41196,191817,88.7386722555126
"4",3,"Ilam",64502,290254,94.634139799367
"5",4,"Jhapa",184552,812650,90.0695584651295

如何获得输入格式的最终​​输出？

我猜你的主要抱怨是关于附加到输出的“行名”和所有字符串周围的引号。

如果是这种情况，请查看参数row.names和quotein write.table()（因此，write.csv()）并将它们设置为FALSE在您编写文件时。

这是一个示例，假设您在 R 中的数据被称为inData.

首先，我们将inData使用write.csv. 注意行名和带引号的字符串。

write.csv(inData, file = "oldfile.csv")

cat(readLines("oldfile.csv"), sep="\n")
# "","id","name","Households","Population","Total.Male","Total.Female"
# "1",0,"Nepal",5427302,26494504,12849041,13645463
# "2",1,"Taplejung",26509,127461,60552,66909
# "3",2,"Panchthar",41196,191817,90186,101631
# "4",3,"Ilam",64502,290254,141126,149128
# "5",4,"Jhapa",184552,812650,385096,427554

这与inData使用我提到的参数设置为相同的内容FALSE：

write.csv(inData, file = "newfile.csv", 
          row.names = FALSE, quote = FALSE)

cat(readLines("newfile.csv"), sep="\n")
# id,name,Households,Population,Total.Male,Total.Female
# 0,Nepal,5427302,26494504,12849041,13645463
# 1,Taplejung,26509,127461,60552,66909
# 2,Panchthar,41196,191817,90186,101631
# 3,Ilam,64502,290254,141126,149128
# 4,Jhapa,184552,812650,385096,427554
