[Rd] dynamic creation of matrix objects (PR#7136)

[cliff at research.telcordia.com]

I am trying to assign the values in a matrix to an object whose name is 
created dynamically, i.e., using eval-parse-text-paste sequence.  It 
seems that only the very last value in the matrix is assigned to the new 
object.  I have included an example below where I create a matrix object 
called "aMat".  I can assign the contents of aMat to another object 
called "thisMat."  However, when I attempt to make a similar assignment 
to a new object called "thatMat", only the last value is returned, when 
queried.  Does anybody know whether this is a bug...or am I doing 
something wrong?
