Arguments

object	metabCombiner object
data	dataset identifier to extract information from; if NULL, extracts information from all datasets

Value

data frame of adduct annotations

Examples

data(plasma30)
data(plasma20)

p30 <- metabData(head(plasma30,500), samples = "CHEAR")
p20 <- metabData(head(plasma20,500), samples = "Red")

p.comb <- metabCombiner(p30, p20, xid = "p30", yid = "p20")

##retrieve all adduct data
adducts <- adductData(p.comb, data = NULL)

##retrieve adduct data from p30
