axis

Here's my code:

qplot(data=sites, x, y, main="Site 349") 
(p <- qplot(data = sites, x, y, xlab = "", ylab = ""))
(p1 <- p + geom_smooth(method = "loess",span=0.5, size = 1.5))
p1 + theme_bw() + opts(title = "Site 349")

Some of the LOESS lines and confidence intervals go below zero, but I would like to restrict the graphics to 0 and positive numbers (because negative do not make sense). How can I do this?

I have a couple of questions regarding facetting in ggplot2... Let's say I have a query that returns data that looks like this: (note that it's ordered by Rank asc, Alarm asc and two Alarms have a Rank of 3 because their Totals = 1798 for Week 4, and Rank is set according to Total for Week 4) … >>> More
Show frequencies along with barplot in ggplot2

I'm trying to display frequencies within barplot ... well, I want them somewhere in the graph: under the bars, within bars, above bars or in the legend area. And I recall (I may be wrong) that it can be done in ggplot2. This is probably an easy one... at least it seems easy. Here's the code: p <-… >>> More
