converting data type from data.frame to matrix or vector

[Terrence Murphy <Terrence.Murphy@yale.edu>]

folks,

I'm creating column vectors and matrices of data in SAS and then importing 
them individually into Splus.
When I do this each item has data type "data.frame"  and I want to convert 
some of them into data type "matrix" and others into data type "vector".
Is there a quick and easy way to do this? I've been playing with menu and 
dialog boxes to no avail.
thanks,
