所以简单地说,我几乎不知道如何从CSV文件中生成一个巨大的嵌套列表,目的是以漂亮,整洁的JSON格式输出它。
然而,问题是我的json输出给了每个子列表一个“[]”作为json输出中的数据数组,导致太多的括号“[]”,这有点打乱了下一步的过程。
我读了一点关于这一点,并有漂亮的和auto_unbox只有远程一对夫妇括号。
jsonlite::toJSON(updated_nested_lists, pretty=TRUE,auto_unbox = TRUE)
所需的json应该如下所示:
我的json现在看起来像这样
我认为这意味着我应该在某些级别上解包嵌套列表以实现这一点。但是我被困在如何为特定的列表从里到外解包它们上,当我用unlist播放“orders”子列表时,它有点把所有的东西都打碎了,丢失了最里面的数据结构。我想这样做的完整数据(相同的结构,大得多)
最小可重复数据如下:
