varianceGraph

A fit object, typically created by the <code>fit</code> generic function.

Add a trend line to help assess the trend of the residuals. See
    specific method written for the <code>fit</code> argument.

trend

When set to the default <code>TRUE</code>, ensures a trellis device is active with
   limited color scheme. Namely <code>background</code>,
   <code>strip.shingle</code>, and <code>strip.background</code> are each set to <code>"white"</code>.

cgtheme

Can be one of three values:

   [object Object],[object Object],[object Object]

device

Additional arguments, depending on the specific method written for
    the object.  See the method-specific documentation for additional
    details.

Create an equal variance assessment graph of the residuals of a fitted object
  from the <pkg>cg</pkg> package

cg is comprehensive data analysis software, and stands for
 "compare groups." Its genesis and evolution are driven by common needs to
 compare administrations, conditions, etc. in medicine research &
 development. The current version provides comparisons of unpaired
 samples, i.e. a linear model with one factor of at least two levels.
 Good data graphs, modern statistical methods, and useful displays of
 results are emphasized.
