A histogram of image intensity in 'param'
is plotted
with the selected background cutoff similar to the function
plotDens
. Both functions can be used to examine the uniformity
of results from an imaging experiment and to interactively check the
paramaters passed to getBgnd
to determine a suitable background
cutoff value.
The plot is returned as an invisible lattice
object.
