normalise_obj

R Documentation

Normalise a JSON-list.

Description

This function normalises a JSON-list. The concept of JSON-list is here defined as an ordinary R list object whose elements are either all named or none is named. These lists map naturally to JSON elements: objects and arrays. What this function does is wrap certain elements of the nested list obj in list() to make the tree structure of the obj list homologous across different responses. This makes all responses of the same entity type (studies, associations, variants or traits) homologous and hence joinable with family functions lst_*_join.

Usage

normalise_obj(obj, resource_url)

Arguments

`obj`	A JSON-list. This is just an ordinary list as returned by `gc_request` or `gc_request_all`.
`resource_url`	The URL endpoint used to obtain the JSON-list `obj`. This is used to infer the type of GWAS entity returned. See `object_type_from_url` for more details.

Details

This normalisation is GWAS object type specific. The parameter resource_url should be mappable to either studies, associations, variants or traits by object_type_from_url.
