maxLagMissVal: Get maximum lag of missing values

In geoTS: Methods for Handling and Analyzing Time Series of Satellite Images

Get maximum lag of missing values

Description

This function computes the maximum amount of consecutive missing values in a vector. This quantity is also known as maximum lag, run, or record, and can be used as a rough estimate of the quality of a dataset.

Usage

maxLagMissVal(x, type = c("NA", "numeric"), value)

Arguments

x	numeric vector.
type	character specifying the type of missing value to consider. Default is type="NA"; when type="numeric", value must be provided.
value	numeric giving a figure to be used to fill missing values; often as part of a pre-processing, missing values in a dataset (vector, time series, etc.) are fill in with pre-established values.

Value

A list containing:

maxLag	numeric giving the maximum lag of missing values in x
x	numeric vector with the original data
value	a numeric when type=numeric, NA otherwise
