order.index.gene.data: Order Index Gene Data

In GRIN2: Genomic Random Interval (GRIN)

Order Index Gene Data

Description

This function order and index gene annotation data by chromosome on which the gene is located, gene start, and end positions.

Usage

order.index.gene.data(gene.data)

Arguments

gene.data

data.frame with gene annotation data either provided by the user or retrieved from ensembl BioMart database using get.ensembl.annotation function included in the GRIN2.0 library. data.frame should has four columns that include "gene" which is the ensembl ID of the annotated genes to which the lesion data will be overlapped, "chrom" which is the chromosome on which the gene is located, "loc.start" which is the gene start position, and "loc.end" the gene end position.

Value

A list with the following components:

gene.data	Input gene annotation data
gene.index	data.frame with two columns of ordered row start and row end based on the number of genes annotated to each chromosome.
