51  ppp

Chapter 51 outlines the S3 methods currently not planned for the class 'ppp' (Chapter 36).

51.1 na.*()

Other than the S3 methods na.omit.ppp() and na.exclude.ppp() (Section 36.1), the author does not implement the S3 methods of the generic functions stats::na.fail() and stats::na.pass() to a point-pattern. The author may implement one or both of them in future.
