detect_upset_datatype: Detect the type of the input data for an UpSet plot

In plotthis: High-Level Plotting Built Upon 'ggplot2' and Other Plotting Packages

Detect the type of the input data for an UpSet plot

Description

Inspects the structure of data and returns a classifier string that downstream functions use to select the parsing strategy. When data is an UpsetPlotData object (from prepare_upset_data()) it short-circuits to "upset" immediately.

Usage

detect_upset_datatype(data, group_by = NULL, id_by = NULL)

Arguments

data	A data frame or a named list of element vectors.
group_by	A character string specifying the column name for the set-definition groups. Only meaningful when data is a data frame.
id_by	A character string specifying the column name for instance identifiers. Required when group_by is a single column and data is a data frame.

Value

A character string, one of "long", "wide", "list", or "upset".

"long"

Long-format data — each row records one (set, element) pair.

"wide"

Wide-format data — each row is an element and each set has its own logical/0-1 column.

"list"

A named list of element vectors.

"upset"

Already an UpsetPlotData object.
