R help - May 2012 - How to create axis y axis for horizontal bar plot?

Hi, 

i am working on bar plot but i need to generate y axis for horizontal bar
plot.  In the attached diagram x-axis is there with scale 0 to 12 but i need
y axis.  How can i implement it?

Try:
gears = c(3,4,5)
b = barplot(gears, horiz=TRUE)
axis(2, at=b, labels=c('three','four','five'))

# Hi Manish, try this

# locate the y axis central positions
barObj <- plot(factor(mtcars$gear, labels = paste(3:5, "Gears")),
horiz = TRUE)

# create the plot
plot(factor(mtcars$gear, labels = paste(3:5, "Gears")), horiz = TRUE)
# add axes
axis(side = 2, at = c(barObj), labels = FALSE)
