List nodes under a meta node — meta_nodes_list

GET /meta/nodes/{meta_node}/list

meta_nodes_list_node(
  meta_node,
  full_data = TRUE,
  limit = 10,
  offset = 0,
  mode = c("table", "raw")
)

Arguments

meta_node	Name of a meta node (e.g. Gwas). Use `meta_nodes_list` to get the full list of meta nodes.
full_data	When False, only return the id and name fields (their specific names differ in specific nodes) for a node. This is useful if you want your queries to return results faster with smaller amount of data requested.
limit	Max number of items to retrieve.
offset	Number of items to skip. Use `limit` and `offset` in combination to do pagination.
mode	If `mode = "table"`, returns a data frame (a `tibble` as per `tidyverse` convention). If `mode = "raw"`, returns a raw response from EpiGraphDB API with minimal parsing done by `httr`.

Value

Data from GET /meta/nodes/{meta_node}/list
