ggplot2

I'm creating a plot and adding a basic loess smooth line to it.

qplot(Age.GTS2004., X.d18O,data=deepsea, geom=c('point')) + 
geom_smooth(method="loess",se=T,span=0.01, alpha=.5, fill='light blue',color='navy')

The problem is that the line is coming out really choppy. I need more evaluation point for the curve in certain areas. Is there a way to increase the number of evaluation points without having to reconstruct geom_smooth?

The part that has me very excited is that one can use data stored in one's own Google spreadsheet as the data. One just signs into their Google… >>> More

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

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
