R help - Jun 2008 - ggplot facet spacing, wrapping

I'm running into some problems with the spacing of some faceted ggplot
plots.
I have a number of time series faceted to be one above another, but the
scale labels of the y axes all clobber each other at the bottom/top of each. 
for example, try:

qplot(x, y, data = data.frame(x = 1:10, y = 1:10, size = 1:10), facets size ~ .,
size = size) + scale_x_continuous(breaks = 1:10) +
scale_y_continuous(limits = c(0,10))

and notice the 10's and the 0's on the respective Y axes are mushing
each
other.  Is there a way to adjust the spacing of facets in a faceted plot?  

Likewise, what about wrapping, so that if I had say 20 or 30 facets it would
make a grid of facets rather than 30 in a column (or in a row).

thanks,
mike

Not at the moment, but it's on my to do list to be completed this summer.

Again, on the to do list.  You can kind of do it yourself though, if
you really really want it.  The basic idea is as follows:

df <- data.frame(x = 1:10, y = 1:10, size = 1:10)
df <- transform(df,
  xgrid = x %% 4,
  ygrid = y %/% 4
)
qplot(x, y, data=df, facets = xgrid ~ ygrid)
