ggenealogy (version 0.2.0)

plotPathOnAll: Plot a path between two vertices over the full genealogy

Description

This function requires a path and the ig object, and plots the full genealogy with the path highlighted. The image will correctly position the node labels with x-axis representing the node year, and y-axis representing the node path index. Light grey edges between two nodes represent parent-child relationships between those nodes. To enhance the visual understanding of how the path-of-interest fits into the entire graph structure, the nodes within the path are labelled in boldface, and connected with light-green boldfaced edges.

Usage

plotPathOnAll(path, geneal, ig, binVector = sample(1:12, 12), edgeCol = "gray84", pathEdgeCol = "seagreen", nodeSize = 3, pathNodeSize = 3, pathNodeFont = "bold", nodeCol = "black", animate = FALSE)

Arguments

path

path as returned from getPath() or a vector of two variety names which exist in ig

geneal

the full genealogy (in data frame format)

ig

the graph representation of the data genealogy (in igraph format)

binVector

vector of numbers between 1 and length(binVector), each repeated exactly once

edgeCol

color of the non-path edges, default is "gray84"

pathEdgeCol

color of the path edges, default is "seagreen"

nodeSize

text size of the non-path node labels, default is 3

pathNodeSize

text size of the path node labels, default is 3

pathNodeFont

font face of text of the path node labels ("plain", "italic", "bold", "bold.italic"), default is "bold"

nodeCol

color of the non-path node labels, default is black

animate

If the plot will have interactive capabilities, default is FALSE
