[R] Attaching marginal summary plots to the main matrix plot

[Adaikalavan Ramasamy]

Dear helplist, I am trying to visualise a datamatrix together with its
marginal densities.
Suppose dat <- matrix( rnorm(1000), nrow=25 )

 I can the main visual plot using image, levelplot etc. But how do I attach
the plots for rows sums and column sums to the top/bottom and right hand
side of the original plot ?

 The only way I can think of is by using par(mfrow=c(2,2)) command but the
result is not desirable. Is there are useful command(or website advising
how) to do this ? If succesful I am thinking of affixing the boxplots by row
and columns as well. I have gone through the lattice help but am still
confused. Thank you.
