CGR: Chaos Game Representation

Description

Chaos game representation is the depiction of sequence in graphical form. It converts long single dimensional sequence (in this case genetic sequence) into graphical form.

Usage

CGR(data)

Value

This function produces a chaos game representation (CGR) plot and a data frame.

Arguments

data

Input as a nucleic acid sequence of characters from fasta file.

Author

Dr. Anu Sharma, Dr. Dwijesh Chandra Mishra

Details

This function produces visual image of DNA sequence different from the usual linear ordering of nucleotides.
