S3 method for plotting objects of class "cchart.DSnp".
# S3 method for class 'cchart.DSnp'
plot(x, ...)Invisible x.
The plot shows the first-stage counts x1 against the sample index.
Points requiring a second sample are shown as open circles. Points that
signal (at either stage) are shown in red. Horizontal lines mark the
fractional limits.
Note that ucl2 is on the scale of the combined count
x1 + x2. The plot is a simple operational visualization; the
full decision logic is in the returned object.
