extrapolateNA: Extrapolate NA's in a univariate vector

In DoktorMike/datools: A set of useful tools for machine learning consulting using R

Description

Extrapolates NA's in the beginning or the end of a univariate vector. Intermediate NA's that occur between two observed values are not touched. Please use interpolation for that case.

Usage

extrapolateNA(x, len = 3)

Arguments

x	the univariate vector to extrapolate
len	the number of non NA elements to base the extrapolation on which defaults to 3

Value

a vector with the NA's in the beginning and the end extrapolated

Examples

extrapolateNA(c(NA, NA, NA, 4, 5, 6, 7, NA, NA))
extrapolateNA(c(0, NA, NA, 4, 5, 6, 7, NA, NA))
extrapolateNA(c(0, NA, NA, 4, 5, 6, 7, NA, 9))
