dot-applyRadialLayout: Apply radial layout transformation to pedigree coordinates

In ggpedigree: Visualizing Pedigrees with 'ggplot2' and 'plotly'

Apply radial layout transformation to pedigree coordinates

Description

Transforms Cartesian pedigree coordinates (x_pos = horizontal slot, y_pos = generation) into Cartesian coordinates derived from a polar mapping, producing a circular or fan-shaped layout. The transformation maps x_pos to an angular position and y_pos to a radial distance, then converts back to (x, y) via standard polar-to-Cartesian conversion. Family bar positions (x_fam, y_fam) are transformed using the same mapping.

Usage

.applyRadialLayout(ds, config)

applyRadialLayout(ds, config)

Arguments

ds

A data frame containing at minimum x_pos, y_pos, x_fam, and y_fam columns, as produced by calculateCoordinates and .adjustSpacing.

config

A list of configuration options for customizing the plot. See getDefaultPlotConfig for details of each option. The list can include: code_male Integer or string. Value identifying males in the sex column. (typically 0 or 1) Default: 1 segment_spouse_color, segment_self_color Character. Line colors for respective connection types. segment_sibling_color, segment_parent_color, segment_offspring_color Character. Line colors for respective connection types. label_text_size, point_size, segment_linewidth Numeric. Controls text size, point size, and line thickness. generation_height Numeric. Vertical spacing multiplier between generations. Default: 1. shape_unknown, shape_female, shape_male, status_shape_affected Integers. Shape codes for plotting each group. sex_shape_labels Character vector of labels for the sex variable. (default: c("Female", "Male", "Unknown")) unaffected, affected Values indicating unaffected/affected status. sex_color_include Logical. If TRUE, uses color to differentiate sex. label_max_overlaps Maximum number of overlaps allowed in repelled labels. label_segment_color Color used for label connector lines.

Value

The input data frame with x_pos, y_pos, x_fam, and y_fam replaced by their radially transformed equivalents.
