recodeBinary {dinamic}R Documentation

Recode Binary Vectors

Description

This function is called internally by DiNAMIC's peeling function, and by construction the kth entry of binary.vec is 1, where k is described below. If length(binary.vec) = m, then the function produces a binary vector of length m that contains a single contiguous string of 1's, namely the string that contains the 1 in the kth position of binary.vec.

Usage

recodeBinary(binary.vec, k)

Arguments

binary.vec

A binary vector of length m (>= 1) whose kth entry is 1.

k

A positive integer.

Value

A binary vector of length m that contains a single contiguous string of 1's, namely the string that contains the 1 in the kth position of binary.vec.
