Description

Given a hyperframe, this function returns a logical matrix specifying which entries of the hyperframe are missing.

Usage

# S3 method for hyperframe
is.na(x)

Value

A logical matrix with the same dimensions as x.

Details

This function returns a logical matrix, with the same dimensions as the hyperframe x, with the value TRUE in each position where the corresponding entry in the hyperframe is missing.

An entry x[i,j] is deemed to be missing if it is either NA (representing a missing value in an atomic vector) or is an object of class "NAobject" (representing a missing object of a particular class in the spatstat package family).
