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?
