[R] How to create HyCa$NIR and octane like the "yarn" of "pls".
I am a user of package, "pls". I am going to draw the NIR spectra of my own measured data using matplot. Question For example, I have such a csv data, "HyCa.csv", below. Would you please tell me how to create a data like the "yarn". yarn has the structure of "NIR" and "density". That is to say,how to create HyCa$NIR and octane for drawing and analyzing the obtained data.
