The second argument stencil controls "what and how" to plot. stencil=missing (default) plots stand-alone images of z-score and power distributions along the range of sample sizes (see print-method for details on the range).
stencil=1 chooses z-score distributions to plot in stand-along fashion.
stencil=2 chooses power distributions to plot in stand-along fashion.
stencil=3 controls to plot z-score and power distributions paired alongside.
Also, Q0.05, Q01, Q0.5 (median) quantiles are graphed in lines.

signature(x = "powerClass")

Method for function plot for object of S4 class powerClass.

Examples

require(ltable)
data(tdata, package="ltable")
## For better illustration You should increase draw and burnin pars
pres<-MCPower(Counts~smoker +contraceptive +tromb +  
contraceptive*tromb, scale_max=1.5, effect="contraceptive*tromb", 
data=tdata, draw=1000, burnin=300)
plot(pres)
plot(pres, stencil=3)
