What does "index" mean in for example value = "index"?

Good day everyone,

I have a very simple question regarding some terminology.

When getting matrices from the xcmsSet object, I've read there are three options for [value]
value = "into"
value = "maxo"
value = "index" ; which I think is also the default

I've read that "into" is for the integrated peak and "maxo" is for the maximum peak, however I am still confused with regards to what the "index" values mean?
Any help would be greatly appreciated.

cheers,
Greg

You get the peak indices, which refer to the @peaks table of the xcmsSet object.
