ggpedigree
provides modern tools for visualizing pedigree structures using both ‘ggplot2’ and ‘plotly’. It is designed to work seamlessly with the BGmisc
package for simulated or empirical pedigree data, and extends the plotting capabilities of the base-graphics functions in kinship2
.
The package supports:
Static, publication-ready pedigree plots using the ggplot2
framework
Interactive pedigree visualizations using plotly
Layout customization, complex mating structures, and duplicated individuals
ggpedigree
is useful in behavior genetics, kinship analysis, and any research involving complex pedigree data.
You can install the released version of ggpedigree from CRAN with:
install.packages("ggpedigree")
To install the development version of ggpedigree
from GitHub use:
# install.packages("devtools") devtools::install_github("R-Computing-Lab/ggpedigree")
Here is a basic example of how to use ggpedigree
to visualize a pedigree structure. The potter
dataset contains simulated pedigree data for the Weasley family from the Harry Potter series.
ggPedigree(potter, famID = "famID", personID = "personID" )
