R help - Apr 2012 - How to change color of bar based on y value of y axis?

Hi, 


I m working on bar chart. 

*Input file:*
index	-5	1
index	-4	3
index	-3	2
index	-2	10
index	-1	7
index	0	2
index	1	1

barplot(t(as.matrix(i[3])), ylab= "value", main =
"testdata", beside=TRUE,
col=c("burlywood1"),horiz=TRUE,cex.names=0.8,names.arg=t(as.matrix(i[,2])))

But i need to change the color of bar where value of  y = -3 dynamically.
How can i implement it.

You still failing to provide reproducible examples.

Maybe you want this.

x<-sample(1:10, 5)
barplot(x, col=c("burlywood1"))
set.seed(333)
y<-sample(-3:0, 5, replace=T)
barplot(x, col=c("burlywood1", "red")[(y==-3)+1])
