In R, how to plot bars only in a certain interval of data?

My problem is very simple. I have to plot a data series in R, using bars. Data are contained in a vector vet.

I've used barplot, that plots my data from the first to the last: barplot(vet), and everything was fine.

Now, on the contrary, I would like to plot not all my data, but just a part of them: from 10% to the end. How could I do this with barplot()? How could I do this with plot()?

Thanx

It is not clear exactly what you want to do.

If you want to plot only a subset of the bars (but the whole bars) then you could just subset the data before passing it to barplot.

If you want to plot all the bars, but only that part beyond 10% (not include 0) then you can do this by setting the ylim argument. But it is very discouraged to do a barplot that does not include 0. You may be better off using a dotplot instead of a barplot if 0 is not meaningful.

If you want the regular plot, but want to exclude plotting outside of a given window within the plot then the clip function may be what you want.

The gap.barplot function from the plotrix package may also be what you want.

You need to subset your data before plotting:

##Work out the 10% quantile and subset
v = vet[vet > quantile(vet, 0.1)]
