ggmanh: A package for visualization of GWAS results.

Description

ggmanh provides flexible tools for visualizing GWAS result for downstream analysis.

Details

Manhattan plot is commonly used to display significant Single Nucleotide Polymorphisms (SNPs) in Genome Wide Association Study (GWAS) This package comes with features useful for manhattan plot creation, including annotation with ggrepel, truncating data for faster plot generation, and manual rescaling of the y-axis. The manhattan plot is generated in two steps: data preprocessing and plotting. This allows the user to iteratively customize the plot without having the process the GWAS summary data over and over again. Currently, data.frame and GRanges from GenomicRanges are supported.
