Summarizing a Quadrature Scheme

Description

summary method for class "quad".

Usage

  ## S3 method for class 'quad':
  summary(object, ..., checkdup=FALSE)
  ## S3 method for class 'quad':
  print.summary(x, ..., dp=3)

Arguments

object A quadrature scheme.
... Ignored.
checkdup Logical value indicating whether to test for duplicated points.
dp Number of significant digits to print.
x Object of class "summary.quad" returned by summary.quad.

Details

This is a method for the generic summary for the class "quad". An object of class "quad" describes a quadrature scheme, used to fit a point process model. See quad.object) for details of this class.

summary.quad extracts information about the quadrature scheme, and print.summary.quad prints this information in a comprehensible format.

  # save the summary
  s <- summary(Q)
  # print it
  print(s)
  s
  # extract total quadrature weight
