Plot lmList Confidence Intervals

Description:

     A Trellis dot-plot of the confidence intervals on the linear model
     coefficients is generated, with a different panel for each
     coefficient. Rows in the dot-plot correspond to the names of the
     'lm' components of the 'lmList' object used to produce 'x'. The
     lower and upper confidence limits are connected by a line segment
     and the estimated coefficients are marked with a '"+"'. The
     Trellis function 'dotplot' is used in this method function.

Usage:

     ## S3 method for class 'intervals.lmList':
     plot(x, ...)

Arguments:

       x: an object inheriting from class 'intervals.lmList',
          representing confidence intervals and estimates for the
          coefficients in the 'lm' components of the 'lmList' object
          used to produce 'x'. 

     ...: optional arguments passed to the Trellis 'dotplot' function. 

Value:

     a Trellis plot with the confidence intervals on the coefficients
     of the individual 'lm' components of the 'lmList' that generated
     'x'.
