x	a compositional dataset
...	a series of new labels assigned to strings or vectors of strings denoting the components that need amalgamating

Value

an object of the same class as X with fewer components

Examples

data(Namib)
HMcomponents <- c("zr","tm","rt","TiOx","sph","ap","ep",
                  "gt","st","amp","cpx","opx")
am <- amalgamate(Namib$PTHM,feldspars=c("KF","P"),
                 lithics=c("Lm","Lv","Ls"),heavies=HMcomponents)
plot(ternary(am))
