[R] Graphical representation of a matrix ?

[Jonathan Baron]

Another way to represent matrices is matplot.  If you use the
type="l" option, it plots parallel lines, one for each column.
(So you need to t() the matrix if you want the rows.)

You can also use lines() over and over, probably with apply()
[but I haven't tried that since matplot does everything I need].

Another thing is plot.table().  You can convert the matrix to a
table and use this.  The result is very nice.  Try also col=T for
an option.
