R语言中RStudio中文读取乱码的解决方法

这期内容当中小编将会给大家带来有关R语言中RStudio中文读取乱码的解决方法，文章内容丰富且以专业的角度为大家分析和叙述，阅读完这篇文章希望大家可以有所收获。

RStudio中使用rjson包读取处理json数据时，遇到中文会显示为 ""等类似乱码。

解决方案，在R语言终端中输入以下命令完美解决。

Sys.setlocale(category="LC_ALL",locale="en_US.UTF-8")

将以下JSON数据保存为json格式文件（注意文件编码为UTF-8）

{"ID": ["1", "2", "3", "4", "5", "6", "7", "8"],"Name": ["Rick", "Dan", "Michelle", "Ryan", "Gary", "Nina", "Simon", "Guru"],"Salary": ["623.3", "515.2", "611", "729", "843.25", "578", "632.8", "722.5"],"StartDate": ["1/1/2012", "9/23/2013", "11/15/2014", "5/11/2014", "3/27/2015", "5/21/2013", "7/30/2013", "6/17/2014"],"Dept": ["IT部门", "Operations", "IT", "HR人力资源部", "Finance", "IT", "Operations", "Finance"]}

使用rjson包读取json数据，已下3行命令：

library("rjson")result_json <- fromJSON(file = "comment.json")result_json

第一行：加载rjson包；

第二行：使用函数fromJSON读取本地json文件；

第三行：输出结果；

在未解决乱码之前输出结果是：

$ID[1] "1" "2" "3" "4" "5" "6" "7" "8"$Name[1] "Rick"     "Dan"      "Michelle" "Ryan"    [5] "Gary"     "Nina"     "Simon"    "Guru"    $Salary[1] "623.3"  "515.2"  "611"    "729"    "843.25" "578"   [7] "632.8"  "722.5" $StartDate[1] "1/1/2012"   "9/23/2013"  "11/15/2014" "5/11/2014" [5] "3/27/2015"  "5/21/2013"  "7/30/2013"  "6/17/2014" $Dept[1] "IT"              [2] "Operations"                      [3] "IT"                              [4] "HR"[5] "Finance"                         [6] "IT"                              [7] "Operations"                      [8] "Finance"

通过命令解决中文输出问题后，输出结果完美解决中文问题。

$ID[1] "1" "2" "3" "4" "5" "6" "7" "8"$Name[1] "Rick"     "Dan"      "Michelle" "Ryan"    [5] "Gary"     "Nina"     "Simon"    "Guru"    $Salary[1] "623.3"  "515.2"  "611"    "729"    "843.25" "578"   [7] "632.8"  "722.5" $StartDate[1] "1/1/2012"   "9/23/2013"  "11/15/2014" "5/11/2014" [5] "3/27/2015"  "5/21/2013"  "7/30/2013"  "6/17/2014" $Dept[1] "IT部门"       "Operations"   "IT"          [4] "HR人力资源部" "Finance"      "IT"          [7] "Operations"   "Finance"
