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)))
