Dear list,

I'm having trouble to see how my elements on a 4 dimensional array are
listed.

For example, I generated the following array:

junk.melt=melt(occ.data,id.var=c("Especie", "Site", "Rep", "Año"),
measure.var="Pres")
y=cast(junk.melt, Site ~ Rep ~ Especie ~ Año)

Now, I want to be able to look at how my species (Especie) are listed, in
which order.

 I found that they are not listed in alphabetical order (using rudimentary
data management skills). Is there a way to reorder them in alphabetical
order? and if not, how do I see the order of my 277 species?

Thank you,
