flowchart: Create a flowchart object

In Gmisc: Descriptive Statistics, Transition Plots, and More

Create a flowchart object

Description

This function initializes a flowchart object, which is essentially a list of boxes with the class 'Gmisc_list_of_boxes'. It serves as the starting point for the S3 pipeline, allowing for fluent chaining of ['align'], ['spread'], ['move'], and ['connect'] operations.

Usage

flowchart(..., default_box_fn = boxGrob)

Arguments

...	Either a set of ['boxGrob'] objects, text strings, or lists of these. Text strings will be automatically wrapped in ['boxGrob'] (or 'default_box_fn').
default_box_fn	The function to use for converting text/content into a box (default: ['boxGrob']).

Value

A 'list' of class 'Gmisc_list_of_boxes'.

fc <- flowchart(
  start = "Start",
  process = "Process",
  end = "End"
)

# Use the pipeline

  align(axis = "y") |>
