Fred,
[from help on pairs() ]:
...
Arguments:
x: the coordinates of points given as columns of a matrix.
So yes, pairs will do what you ask. See ?pairs for more info.
Also you might consider the alternative function from the lattice package:
> library(lattice) #load lattice graphics package
> ?splom #help for splom()
Which is called differently using a formula interface.
