In Nisus-Liu/vava: some frequently-used functions for me

Description

imputed by HoltWinters method, forward or afterward

Usage

impute_es(x, extent = numeric(), forward = FALSE, methods = "HoltWinters",
  alpha = NULL, beta = NULL, gamma = NULL, file = paste(getwd(),
  "/HoltWintersAns.csv", sep = ""), out = TRUE)

Arguments

x	a vector, should converted to ts if not a annual time series.
extent	specify how long to predict forward or afterward.
forward	if TRUE, will predicts extent values forward, default is FALSE.
methods	method for impute, now only HoltWinters.
alpha	reference to HoltWinters.
beta	ditto.
gamma	ditto.
file	where to store answers.
out	export answers if TRUE.
