How to add values on bar of grouped bar plot using mtext?

How to write values on bars using mtext?

Grouped Bar Plot
counts <- table(mtcars$vs, mtcars$gear) barplot(counts, main="Car Distribution by Gears and VS",xlab="Number of Gears", col=c("darkblue","red"),legend = rownames(counts), beside=TRUE, horiz=TRUE)

mtext(counts ) # But poistion is not at each bar.

How can i put corresponsing values on each bars of  plot?

 Distribution by Gears and VS",xlab="Number of Gears",
 col=c("darkblue","red"),legend = rownames(counts), beside=TRUE, horiz=TRUE)


mtext(text=counts,las=1,side=2,outer=FALSE,at=p1)
A.K.

I think mtext write on margin but i need on values on bars. I found text is more useful. How can i use text to write on it.

Try this:
counts <- table(mtcars$vs, mtcars$gear)
p1<-barplot(counts, main="Car
 Distribution by Gears and VS",xlab="Number of Gears",
 col=c("darkblue","red"),legend = rownames(counts), beside=TRUE, horiz=TRUE,xlim=c(0,14))
text(counts,p1,formatC(counts,digits=2),pos=4)
