select.blocks.gt.length: Select blocks of TRUE values of sufficient length.

In ECA-D/climind: ECAD Implementation of Climdex Routines

Select blocks of TRUE values of sufficient length.

Description

Produces a sequence of booleans of the same length as input, with sequences of TRUE values shorter than n replaced with FALSE.

This function takes a series of booleans and returns a sequence of booleans of equal length, with all sequences of TRUE of length n or shorter replaced with sequences of FALSE. NA values are replaced with na.value.

Usage

select.blocks.gt.length(d, n, na.value = FALSE)

Arguments

d	Sequence of booleans.
n	Longest sequence of TRUE to replace with FALSE.
na.value	Values to replace NAs with.

Value

A vector of booleans, with the length n or less sequences of TRUE replaced with FALSE.

Examples

## Return only the first sequence of TRUE... second sequence will be FALSE.
foo <- select.blocks.gt.length(c(rep(TRUE, 4), FALSE, rep(TRUE, 3)), 3)
