Circos plot of SNP distribution across chromosomes

Circos plot of SNP distribution across chromosomes

Usage

plot_snp_circos(genome_ranges, gene_ranges, marker_ranges)

Arguments

genome_ranges

A GRanges object with chromosome lengths.

gene_ranges

A GRanges object with genomic coordinates of all genes in the genome.

marker_ranges

Genomic positions of SNPs. For a single trait, a GRanges object. For multiple traits, a GRangesList or CompressedGRangesList object, with each element of the list representing SNP positions for a particular trait.

Value

A ggplot object with a circos plot of molecular marker distribution across chromosomes.

Examples

data(snp_pos)
data(gene_ranges)
data(chr_length)
p <- plot_snp_circos(chr_length, gene_ranges, snp_pos)
