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
