[R] Datapoint tracking in scatterplot from plot() used on plsr() objects

[CG Pettersson]

Dear all,
I am working with PLS-regression using plsr() from the pls package. I have a medium sized dataset with 223 rows, ten reference columns and 192 columns with measurement data from an "electronic nose".

There is a convenient way of inspecting what you have done in the calls to plsr() by typing plot(object) which results in a scatterplot predicted/measured. How do I track what row in the dataset is what point in the scatterplot? I have tried to read the documentation for plot() but don´t find the solution, probably because I don´t understand it :(. I am quite sure it is possible as I have seen something like that in other uses of plot() but I can´t find where.

Med vänlig hälsning/Best regards
