That's one way to look at it. The other interpretation is that the
author(s) of the functions you tried to use do not consider what you
are doing "basic".
If you are interested in simpler alternatives, I would suggest something like
barchart(Group ~ Percentage | factor(a), test, origin = 0,
panel = function(x, y, ...) {
panel.grid(h = 0, v = -1)
panel.barchart(x, y, ...)
ltext(x, y, labels=round(x, 0),
cex=.7, col="black", font=2, pos=4)
})
