### Describe the enhancement requested Stack Overflow Reference: https://stackoverflow.com/questions/75861075/is-there-a-way-to-read-a-nested-column I have a bunch of Newline-delimited JSON files that I want to read into R using the arrow package. One of the parameters in the file is nested. The potential nested values are quite big and messy and I would prefer to only select the nested parameters I actually need. Here is an example of the data I am working with: ``` # Bring in libraries suppressMessages(library(arrow)) suppressMessages(library(data.table)) # Make data tf <- tempfile() on.exit(unlink(tf)) writeLines(' { "hello": 3.5, "world": false, "yo":{"param1":"duck1","param2":"duck2"} } { "hello": 3.25, "world": null, "yo":{"param1":"duck3","param2":"duck4"} } { "hello": 0.0, "world": true, "yo":{"param1":"duck5","param2":"duck6"} } ', tf, useBytes = TRUE) df <- read_json_arrow(tf) ``` This is the result of what I just read in:  ``` read_json_arrow(tf, col_select = "yo") ``` I can also read in the "yo" column. The results is below:  But I am having trouble reading in the "yo.param1" data element:  Any ideas on how I might read this nested column in and avoid reading in the entire column? ### Component(s) R -- This is an automated message from the Apache Git Service.
