The heading for the graph is taken from the cgPairedDifferenceData
object,
which
prepareCGPairedDifferenceData
sets from its analysisname
argument.
The label for the Y-axis is taken from the cgPairedDifferenceData
object,
which
prepareCGPairedDifferenceData
sets from its endptname
argument.
The number of decimal places printed in the ticks on the Y-axis is taken
from the cgPairedDifferenceData
object,
which prepareCGPairedDifferenceData
sets from its digits
argument.
The minimum and maximum values from the range of the residuals are respectively labeled in the bottom and top left corners of the graph region.
qqGraph.cgPairedDifferenceFit
returns
an invisible NULL
. The main purpose is the side
effect of graphing to the current device.
