There's no such function, I presume you mean barchart.

I'm a bit confused, because a vertical barchart would normally have a
categorical variable on the x-axis, yet you talk of numeric labels for
them. Please provide a reproducible example. For numeric axes
specifying a reversed xlim (e.g. xlim = c(10, 0) ) should work.
