[R] expand.grid function

[dxc13]

useR's,

I have used expand.grid() several times and like the results it gives me.  I
am now trying something with it that I have not been able to get to work. 
For any n column matrix I would like to run this function on those n columns
and store the results.
For example, if my matrix has 1 column then this is just expand.grid(x =
column1).  If my matrix has two columns, then I want expand.grid(x =
column1, y = column2), and so on for any number of columns...

In a program I am writing, the user can specify any matrix.  Does anyone
know of a way for R to calculate this based on what the input matrix is? 
e.g. if this user gives a 3 column matrix, I want to be able to perform
expand.grid() on these 3 columns without having to hard code it b/c I want
to have this small function embedded in my code and the results stored as a
variable.

If this isn't clear, I can try to be more detailed.  Thank you for any
thoughts.
