如何在R中读取未知编码的csv数据 [英] How to read csv data with unknown encoding in R

问题描述

我有一个 .csv 数据，我可以从网页上查看它，但是当我将它读入 R 时，有些数据无法显示.数据在这里home.ustc.edu.cn/~lanrr/data.csv

I have a .csv data, and I could view it from a webpage, but when I read it into R, some of the data couldn't be showed. The data is available here home.ustc.edu.cn/~lanrr/data.csv

mydata = read.csv("http://home.ustc.edu.cn/~lanrr/data.csv", header = T)
View(mydata)  # show something like this:
# 9:39:37   665 600160  �޻��ɷ�  ����    ����    8.050   100 805.00  ��ȯ �ɽ�        
  ��ȯ����   E004017669  665
  2 9:39:38 697 930 ��������    ����    ����    4.360   283 1233.88    
  ����  �ɽ� ����Ʒ����   680001369   697

数据中包含一些中文单词，但是如果我需要更改编码或做其他事情，我没有，以前有人遇到过这个问题吗?

The data contains some Chinese words, but I don't if I need to change the encode or do some other things, has anyone meet this problem before?

mydata = read.csv("http://home.ustc.edu.cn/~lanrr/data.csv", 
                   encoding = "UTF-8", header = T, stringsAsFactors = F)
View(mydata)

我最后是这样做的:

Sys.setlocale("LC_COLLATE", "Chinese")
Sys.setlocale("LC_CTYPE", "Chinese")
Sys.setlocale("LC_MONETARY", "Chinese")
Sys.setlocale("LC_TIME", "Chinese")
Sys.setlocale("LC_MESSAGES", "Chinese")
Sys.setlocale("LC_MEASUREMENT", "Chinese")

推荐答案

首先，那个 csv 文件是用 GBK 编码的不是 UTF-8，所以代码应该是:

First, that csv file in encoded in GBK not UTF-8, so the code should be:

mydata <- read.csv("http://home.ustc.edu.cn/~lanrr/data.csv", 
                    encoding = "GBK", 
                    header = TRUE, 
                    stringsAsFactors = FALSE)

第二，如果你的env不是中文(简体)，你应该set_locale比如(我的例子os是windows 7)

Second, if your env is not Chinese (Simplified), you should set_locale such as (my example os is windows 7)

Sys.setlocale(category = "LC_ALL", locale = "Chinese (Simplified)")

然后显示表格:

fix(mydata)
