R help - Jan 2009 - Adding vertical line to histogram and qplot "stacked" plot

R-users it appears I am leaning on your knowledge once again.  Is there any way
to add a vertical line to a histogram and qplot "stacked" plot?  Here
is my current attempt:
 
"qplot" approach attempt:
qplot(Run, data = data_dataframe, breaks = breaks, fill = Temperature, main =
short_title) + scale_x_continuous("Data") +
scale_y_continuous("Freq")
+  scale_fill_discrete("Temperature") + scale_fill_manual(values =
c(LOW = "blue", AMB ="black", HIGH = "red")) + 
geom_abline(v = HighVal, col = "dodgerblue3", lty="dotdash")
 
 
"hist" approach attempt:
hist(data_dataframe, breaks = breaks,  col = "dodgerblue3",
xlab="Data", freq = TRUE, main="") +abline(v = HighVal, col
= "dodgerblue3", lty="dotdash")  
 
Neither seem to be working.  I think I am missing something small to get this to
work. 
 
Thank you again for any feedback you can provide.

Check Hadley's page, there's a few examples there. Good luck

Are you using ggplot2?  It uses that notation of adding elements to a 
plot.  Classic graphics doesn't, so you would just give the different 
commands separately on each line, e.g.

hist(data_dataframe, breaks = breaks,  col = "dodgerblue3",
xlab="Data",
freq = TRUE, main="")

abline(v = HighVal, col = "dodgerblue3", lty="dotdash")
