In pedMermaid: Pedigree Mermaid Syntax

pedMermaid

R package pedMermaid generates Mermaid syntax for creating a pedigree flowchart in Markdown and R Markdown, from a pedigree data frame.

You can install the development version of pedMermaid like so:

devtools::install_github('nilforooshan/ggroups')

This is a basic example of a pedigree flowchart created by the Mermaid syntax generated by the R package pedMermaid.

library(pedMermaid)
ped <- data.frame(ID = 1:7,
                  SIRE = c(0, 0, 1, 0, 3, 0, 5),
                  DAM = c(0, 0, 2, 2, 4, 0, 6))
x <- mermaid_md(ped)
# cat(x, sep = "\n") # Display the output syntax on-screen

    1 & 2 --> 3
    2 --> 4
    3 & 4 --> 5
    5 & 6 --> 7
