Produces side-by-side QQ plots. An optional simulated confidence envelope can be included in each plot.

a function to extract the desired quantity from x.
a logical value. If TRUE a level confidence
envelope is simulated for each QQ plot.
a logical value. If TRUE the plot is drawn using
the absolute values.
a positive integer value giving the number of samples to compute in the simulation of the confidence envelope.
a numeric value between 0 and 1 specifying the confidence level for the envelope.
a non-negative integer value specifying the number of extreme points to identify.
a logical value. If TRUE, a QQ line is included in the
plot.
additional arguments are passed to
xyplot.
the trellis object is invisibly returned.
