Abstract

Summary: Two functions for pedigree-drawing available in R (http://www.r-project.org): plot.pedigree in kinship and pedtodot in gap are described. The latter requires graphviz (http://www.graphviz.org). They can produce many pedigree diagrams quickly into a single file, serving as alternatives to programs that only offer interactive use. Availability: Packages kinship and gap are available from http://cran.r-project.org. Contact: jinghua.zhao@mrc-epid.cam.ac.uk
