This prepanel function is defined so as to allow room for all confidence intervals plotted in a lattice display. Note, both lower and upper must be passed directly to `xyplot`

as they will be passed down to the prepanel function.

prepanel.ci(x,y,subscripts, lower,upper)

`x,y` |
Data from the call to |

`subscripts` |
Variable used to created the juxtaposed panels. |

`lower, upper` |
95% lower and upper bounds of |

A list giving the ranges and differences in ranges of x and the lower and upper bounds of y.
