Display a stopping rule graphically as a curve
## S3 method for class 'rule.bin'

smooth = TRUE,

)
x |
A |
smooth |
Binary indicator of whether stopping rule boundary should be smoothed by linear interpolation between evaluation points |
xlim |
The x limits (x1, x2) of the plot. Note that x1 > x2 is allowed and leads to a ‘reversed axis’. |
ylim |
The y limits of the plot. |
xlab |
The title for the x axis |
ylab |
The title for the y axis |

Other options to be passed to generic |
No return value; function solely generates a plot
