Subject: problem barplot width
In-Reply-To: <AANLkTimpnfVE_7QQFmh-OnNORo0Vi6Gi4nFXUz4wU=Xi@mail.gmail.com>
The help page of barplot says:
width: optional vector of bar widths. Re-cycled to length the number
of bars drawn. Specifying a single value will have no
visible effect unless ?xlim? is specified.
Following your code, have a look at these examples, which might help to
understand:
barplot(d,col=barcol,ylim=c(min(d-s*1.25),max(d+s*1.25)),space=2)
barplot(d,col=barcol,ylim=c(min(d-s*1.25),max(d+s*1.25)), width = c(1,
3, 2))
barplot(d,col=barcol,ylim=c(min(d-s*1.25),max(d+s*1.25)), width = 0.01,
xlim = c(0,1))
Hope this helps,
Mathieu.
