Display or construct a compact statistical summary of a generalized variance chart, including design dimensions, Phase I and Phase II subgroup counts, control-limit method, covariance source, descriptive statistics, and signaled subgroups.

Usage

# S3 method for class 'cchart.GV'
print(x, digits = max(3L, getOption("digits") - 3L), ...)

# S3 method for class 'cchart.GV'
summary(object, ...)

# S3 method for class 'summary.cchart.GV'
print(x, digits = max(3L, getOption("digits") - 3L), ...)

Arguments

x

An object of class "cchart.GV" or "summary.cchart.GV".

digits

Number of significant digits used for numerical output.

...

Additional arguments passed to the summary print method; otherwise currently unused.

object

An object of class "cchart.GV".

Value

summary.cchart.GV() returns an object of class "summary.cchart.GV". The returned list contains call, dimensions, subgroups, method, limits, covariance, statistics, and signals. The print methods return their input invisibly.
