Hello,
I know nothing about the plsr package but in the data.frame 'gasoline'
the column NIR is numeric and in 'lid_allt2' the column lid_nose is
character. Maybe you need
lid_allt2$lid_nose <- as.numeric(lid_allt2$lid_nose)
but I really don't know if this is the problem.
I have no idea either, but surely your suggestion should be:
lid_allt2$lid_nose <- as.numeric(as.character(lid_allt2$lid_nose))
Actually no, I also thought of that but str(lid_allt2) doesn't say that
lid_nose is a factor, it says "chr".

or (better):
lid_allt2$lid_nose <-
with(lid_allt2,as.numeric(levels(lid_nose))[lid.nose])
cheers,
Rolf
