snp.plotter

snp.plotter is an R package for producing high-quality plots of results from genetic association studies. It allows the display of linkage disequilibrium (LD) plots using either the r2 or D' LD metric and provides options for setting the X-axis, specifying plot labels, colors, symbols, and LD heatmap color scheme. The package can plot single SNP and/or haplotype data and multiple sets of results simultaneously. R is a free software environment for statistical computing and graphics available for most platforms. The package offers a simple and appealing way to convey both association and LD information in a single graphic for genetic association studies.
