Combine annotation records (rows) based on a key. All records with the same key will be combined. A number of helper functions are provided for common approaches to merging records.

Usage

combine_records(
  group_by,
  default_fcn = .collapse(separator = " || "),
  fcns = list(),
  ...
)

Arguments

group_by

(character) The column used as the key for grouping records.

default_fcn

(function) The default function to use for summarising columns when combining records and a specific function has not been provided in fcns. The default is .collapse(separator = " || ").

fcns

(list) A named list of functions to use for summarising named columns when combining records. Names should correspond to the columns in the annotation table. The default is list().

...

Additional slots and values passed to struct_class.

Value

A combine_records object with the following output slots:

updated(annotation_source) The input annotation source with the newly generated column.

Details

This object makes use of functionality from the following packages:

  • dplyr

Inheritance

A combine_records object inherits the following struct classes:

[combine_records] -> [model] -> [struct_class]
