pairs(wines[,1:3], pch = wine.classes, col = wine.classes)
Error in pairs.default(wines[, 1:3], pch = wine.classes, col = wine.classes) :
object 'wine.classes' not found.
I am new to the R community, and trying to teach myself to do Chemometrics using R. I am using the textbook, Chemometrics With R and it has an R package "ChemometricsWithR". When I try to plot the above pairs (wines[.....) it returns an error in pairs. I would be happy to learn why it is not working and what the work around is.
Thanks in advance
