How to adjust the height of a tile in a geometric slab?

I am trying to make a plot with ggplot2, but I am struggling with geotag. Since I am using this geometry for the first time, I carefully looked at the Hadley documentation, but so far I have not been able to get what I am behind it. I want to adjust the width of the tile and the height of the tile. I found how to adjust the tile width in the documentation, but I am struggling with height. The following chart should be used as a starting point:

test <- data.frame(
  x = rep(c(1,3,6),2),
  y = rep(c(1,3), each = 3),
  w = rep(c(.5,2,1), 2),
  z = sample(rep(LETTERS[1:6])))

ggplot(test, aes(x=x, y=y, fill = z)) + geom_tile(aes(width = w))

enter image description here

. "" ( x = 1) 0 1, 1 4. 0 3 3 4. , 0 1,5 1,5 4. , :

test2 <- data.frame(
 x = rep(c(1,3,6),2),
 y = c(0, 0, 0, 1, 3, 1.5),
 w = rep(c(.5,2,1), 2),
 z = sample(rep(LETTERS[1:6])),
 h = c(1, 3, 1.5, 3, 1, 2.5))

ggplot(test2, aes(x=x, y=y, fill = z)) + geom_tile(aes(width = w, heigth = h))

geom_tile height=h ymin ymax -h/2 to h/2. , . @Didzis, , geom_tile . :).

, "" y , , . test2 data.frame,

require(plyr)
# calculate y coordinate accounting for shift in y due to h
test2 <- ddply(test2, .(x), transform, y2 = c(0, head(h,-1)) + h/2)
p <- ggplot(test2, aes(x=x, y=y2, fill = z)) + 
           geom_tile(aes(width = w, height=h))
