如何将列中带有列表的数据框转换为 R 中的 JSON？

Question

I am trying to export a data frame which contains a list in a column, to a JSON and then save it in a format to share it.

So far I am trying to use jsonlite to do the transformation with jsonlite::toJSON()

The data frame can be seen in the following image:

So far I have done this:

x <- jsonlite::toJSON(x = regiones, pretty = TRUE) # "regiones" is the data frame
cat(x)

And I get the following result.

I did not put all the values in the console output.

"codigo_region": "16",
    "geometry": {
      "type": "MultiPolygon",
      "coordinates": [
        [
          [
            [-72.3855, -36.9117],
            [-72.3895, -36.9162],
            [-72.3988, -36.9174],
            [-72.407, -36.9237],
            [-72.4077, -36.9285],
            [-72.419, -36.9305],
            [-72.4227, -36.926],

How can I save the object "x" which is a large json?

Any other recommended approach?

正如 Greg 和 Bruno 所说，使用write_json效果很好。

jsonlite::write_json(path = "path/to/save/your_file.json", x = regiones, pretty = TRUE)
