[R] Facets in ggplot2

Hello, I'm trying to introduce myself to ggplot2. I'm using syntax from the help file, but pasting in my own data. I don't understand the error message I'm getting. Can anyone clue me in? A Google search of this error statement didn't return anything I could recognize as useful.
