R help - Sep 2008 - how to plot monthly mean data showing missing months

Dear R users,

As per my attached script I am ploting monthly mean data which has missing
months.
But in the plot missing months are not shown (plot attached).
Kindly help how to show complete plot (Jan-Dec) with missing months.

Regards,
Yogesh

I don't accept scripts from strangers, but I guess the problem looks like 
this:
df <- data.frame(a=runif(5), b=c("Jan", "Feb",
"Sep", "Jan", "Mar"))
histogram(~a|b, df)     #only four months plotted

df$b <- factor(df$b, levels=month.abb)  #force factor to have all months 
as levels
histogram(~a|b, df, drop.unused.levels=FALSE)   #12 months plotted

Regards,
Richie.
