coordinates2sequence {dnafractal} | R Documentation |
Generates a DNA Sequence Based on an X and Y Coordinate over several iterations
Description
The function takes an X and Y coordinate and a number of bases to be represented in the DNA sequence. The function starts at the provided X and Y coordinates and then works backward, calculating every preceding base in the DNA sequence that led to that particular point in the fractal. Based on the actual X, Y point's coordinate, the base pair corresponding to that coordinate is inferred, and the DNA string will be built up and returned as the product of the function.
