order.index.lsn.data: Order Index Lesion Data

In GRIN2: Genomic Random Interval (GRIN)

Order Index Lesion Data

Description

This function order and index lesion data by lesion type, the chromosome on which the lesion is located , and subject.

Usage

order.index.lsn.data(lsn.data)

Arguments

lsn.data

data.frame with lesion data prepared by the user in a GRIN compatible format. The data.frame should has five columns that include "ID" which is a column with id of the patient affected by the lesion, "chrom" which is the chromosome on which the lesion is located, "loc.start" which is the lesion start position, "loc.end" the lesion end position and "lsn.type" which is the lesion type for example gain, loss, mutation, fusion, etc...

Value

A list with the following components:

lsn.data	Input lesion data
lsn.index	data.frame with row start and row end for each type of lesions affecting each subject on a certain chromosome. For example, if a certain patient is affected by 1 deletion on chromosome 5, row start wil be equal to row end for loss on chromosome 5. However, if the patient is affected by 4 deletions, difference between row.start and row.end will be 3.
