[R] Coord_equal in ggplot2

Dear all,

I'm plotting some points on a graph where both axes need to have the
same scale. See the example below. Coord_equal does that trick but in
this case it wastes a lot of space on the y-axis. Setting the limits of
the y-axis myself was no avail. 

Any suggestions to solve this problem?  

ds <- data.frame(x = runif(1000, min = 0, max = 300000), y = runif(1000,
min = 140000, max = 260000))
ggplot(ds, aes(x = x, y = y)) + geom_point() + coord_equal()
ggplot(ds, aes(x = x, y = y)) + geom_point() + coord_equal() +
scale_x_continuous(limits = c(0, 300000)) + scale_y_continuous(limits =
c(140000, 260000))

than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.
