Visualization of pairwise Linkage Disequilibrium (LD) estimates generated by function pairwiseLD in a LD heatmap for each chromosome using the LDheatmap package (Shin et al, 2006) .
Usage
LDMap(LDmat,gpData,chr=NULL,file=NULL,...)
Arguments
LDmat
Object of class LDmat generated by function pairwiseLD and argument type="matrix"
gpData
Object of class gpData that was used in pairwiseLD
chr
numeric. Return value is a plot for each chromosome in chr.
file
Optionally a path to a file where plot is saved as pdf
...
Further arguments that could be passed to function LDheatmap
