[R] how can I plot bar plots with all the bars (negative and positive) in the same direction????

[Zoppoli, Gabriele (NIH/NCI) [G]]

Dear r-help mailing list,

this seems stupid, but I actually don't find the solution:

if I have a vector of numbers x of length n, ranging, say, from -3 to 4, if I do

barplot (x)

all the values below 0 go downwards, and all the positive values go upward. How can I make them all begin from the minimum pointing upwards?

Thanks!
