从R中的list生成JSON

# 导入jsonlite包
library(jsonlite)

# 创建一个包含多个元素的list
my_list <- list(
  name = "John",
  age = 30,
  is_student = TRUE,
  grades = c(85, 90, 78),
  address = list(
    city = "New York",
    state = "NY"
  )
)

# 将list转换为JSON格式的字符串
json_str <- toJSON(my_list)

# 打印生成的JSON字符串
print(json_str)

{"name":["John"],"age":[30],"is_student":[true],"grades":[85,90,78],"address":{"city":["New York"],"state":["NY"]}}
