[R] intamap plot : specifying cutoffs

Hello all,

A question for plotting of intamap results :

Is it possible, and in so, how, to specify the cutoff points for changing colors
of plots ?

Using the example :
data(meuse)
meuse$value = log(meuse$zinc)
data(meuse.grid)
coordinates(meuse) = ~x+y
coordinates(meuse.grid) = ~x+y
object = interpolate(meuse,meuse.grid,outputWhat = list(mean = TRUE, variance =
TRUE, excprob = 7, excprob = 8, quantile = 0.9, quantile = 0.95),methodName =
"automap")
plot(object)

What arguments can I pass to plot(object) to modify the default cutoffs that
define the color changes on the polts ? I have tried the 'at' and
'cuts' arguments but to no avail.

Thanks very much for your help.
