LDheatmap

An R package implementing a graphical tool for exploring pairwise linkage disequilibria between Single Nucleotide Polymorphisms (SNPs).

Users may optionally include physical locations or genetic map distances of each SNP on the plot. For a description of the features of the package and examples of its use, please see our article in the Journal of Statistical Software.

The LDheatmap R package is available on the Comprehensive R Archive Network website under "contributed packages". See the package vignette for a description of the implementation of the LDheatmap() function in the R grid graphics system, and for examples of the use of this function.

You will have to have R installed on your system to use it. To install LDheatmap you can execute the following command in R:

install.packages("LDheatmap")

Windows users can also install the package via the "Packages" menu item.
