LDheatmap.addGenes

0th

Percentile

Add gene plot to an LDheatmap object.

Retrieve genes from the UCSC Genome Browser, generate the genes plot and add it to an LDheatmap object.

Keywords
hplot
Usage
LDheatmap.addGenes(LDheatmap, chromosome, genome = NULL, genesLocation = 0.02,
splice_variants = TRUE, non_coding = TRUE)
Arguments
LDheatmap

An object of class LDheatmap.

chromosome

A character string that identifies the chromosome.

genome

The genome assembly to use. The default is the most recent human genome assembly on the UCSC genome browser.

genesLocation

The gene plot distance from the LD heat map gene map.

splice_variants

If FALSE, exclude gene splice variants.

non_coding

If FALSE, exclude non-coding genes.

Details

Note: The LDheatmap object should have a non-NULL genetic.distances component. Otherwise the gene map will not be placed correctly. The genes are color coded as follows: black -- feature has a corresponding entry in the Protein Data Bank (PDB); dark blue -- transcript has been reviewed or validated by either the RefSeq, SwissProt or CCDS staff; medium blue -- other RefSeq transcripts; and light blue -- non-RefSeq transcripts.

For assemblies older than hg18, all genes are plotted in grey.

Value

An object of class LDheatmap given as an argument, with the grob LDheatmapGrob modified to inclue the "transcripts" child grob.
