including showing just the lower half of the matrix, jittering markers, and scaling the size
of marker text. For more details, see [

jitter(3)
You can use the
jitter()
option to
add random noise to the points; the
higher the value given, the more
random noise is added. This is
especially useful when numerous
observations have the same (
