Would LOVE to get some help with the "matplot" function.

Here's something that works:
r.matplot([1,2,3], [4,5,6])
This plots (1,3), (2,4), (3,5).
What I want is to plot a second dataset against (1,2,3).
These things don't work:
r.matplot([1,2,3], [[4,5,6],[7,8,9]])
'x' and 'y' must have same number of rows
r.matplot([1,2,3], [[4,7],[5,8],[6,9]])
rpy.RException: Error in as.double.default(y) :
(list) object cannot be coerced to 'double'
r.matplot([[1],[2],[3]], [[4,7],[5,8],[6,9]])
rpy.RException: Error in as.double.default(y) :
(list) object cannot be coerced to 'double'
I'm just not sure how to make a matrix in python that goes
properly into R ... any help appreciated!
