I then make a plot, first of the entire data matrix using the image command Then I plot the first left singular vector which is the first column of the U component of the list that results when you apply SVD to a matrix in R. Then I also plot the first column of the V matrix or the red singular matrix that also is a part of the list that gets created when you apply SVD to a The matrix in R. The left singular vectors appear to show that same pattern that the bromines showed earlier.
