Hi 44whyfrog,
I guess (and it's a wild one) that you have simply typed in the "usage" 
arguments, and these have little or no relation to what is in "data". If 
I were in your pond, I would first try:

names(data)

to see what the names of your columns are. If you do find columns named 
"x" and "y", try:

length(data$x)
length(data$y)

The error message may relate to the fact that you already have an "x" or 
a "y" object hanging around in your workspace, and they have different 
lengths.
