Hi I tried and it is not what im looking ..
I basically issue plot(data$"V1",data$"V2") as the matrix have the two headers..But essentially what I would like is relabel or somehow differentiate row 5 from the rest of the points on the graph. In other words, I wanted to see all the points but at the same time see the particular point (row 5 in this case) on the graph as another point of color in the graph. Please advise.
