Loving R's ggplot2!

So I'm messing around with R for a coursera course I'm taking, and totally loving the ggplot2 library.  Check out this lovely plot of some loan data we got from the course instructor:

 That's a scatterplot with loess smoother + confidence intervals, all done with this simple call:

qplot(x     = FICO
    , y     = ir
    , data  = loansData
    , color = Loan.Length
    , geom  = c('point', 'smooth')
    , ylab  = "Interest Rate"
    , xlab  = "FICO Score"
    )
How awesome is that?
