Unnest data model by the supplied function columns

This function takes a data.table and a vector of column names. These columns are expected to contain lists of function calls. The function 'unnests' these columns such that each function call is represented on its own row in the resulting data.table. This is useful for processing or analyzing the function calls separately.

Usage

unnest_by_fns(dt, cols)

Arguments

dt

A data.table object. The endpoint data model that contains nested function calls.

cols

A character vector of quoted column names in dt that contain the nested function calls.

Value

A data.table in long format, where each row corresponds to a single function call from the nested lists in the specified columns.
