R: removing facet_wrap labels completely in ggplot2
I'd like to remove the labels for the facets completely to create a sort of sparkline effect, as for the audience the labels are irrelevant, the best I can come up with is:

    library(MASS)
    library(ggplot2)
    qplot(week,y,data=bacteria,group=ID, geom=c('point','line'), xlab='', ylab='') + 
         facet_wrap(~ID) + 
         opts(strip.text.x = theme_text(size=0))

So can I get rid of the (now blank) strip.background completely to allow more space for the "sparklines"?

Or alternatively is there a better way to get this "sparkline" effect for a large number of binary valued time-series like this?
