Really your (Mr.deepayan´s)answer is what I expected..thanks a lot...and I like to ask you one more thing..
  Is it possible to do boolean operations in this matrix and plot that also in graphs?
   
  for example 
  1.  a[anja,maya]   Vs   a[vincent,selva]
  means things common between the rows anja&maya  and columns vincent & selva
  2.a[anja,maya]   Vs   a[peter,david]
  and so on...
   
  So in that case whether it is possible to plot in the same graph(since I´m doing different...more than one.. comparisions) or I´ve to plot in a multiple graph..
   
  kindly help me...
  thanks a lot....
   
  with regards,
  eric

Sure, how about

image(a)

If you want the axes to be labelled appropriately, it might be easier with

library(lattice)
levelplot(a)

or perhaps

levelplot(a, scales = list(x = list(rot = 90)))
