-#' where days in the past are chosen and weighted according to some similarity measures.
+#' Predict next serie as a weighted combination of curves observed on "similar" days in
+#' the past (and future if 'opera'=FALSE); the nature of the similarity is controlled by
+#' the options 'simtype' and 'local' (see below).
#'
-#' The main method is \code{predictShape()}, taking arguments data, today, memory,
-#' predict_from, horizon respectively for the dataset (object output of
-#' \code{getData()}), the current index, the data depth (in days), the first predicted
-#' hour and the last predicted hour.
-#' In addition, optional arguments can be passed:
+#' Optional arguments:
#' \itemize{
-#' \item local : TRUE (default) to constrain neighbors to be "same days within same
-#' season"
-#' \item simtype : 'endo' for a similarity based on the series only,<cr>
+#' \item local: TRUE (default) to constrain neighbors to be "same days in same season"
+#' \item simtype: 'endo' for a similarity based on the series only,<cr>
#' 'exo' for a similarity based on exogenous variables only,<cr>
#' 'mix' for the product of 'endo' and 'exo',<cr>
#' 'none' (default) to apply a simple average: no computed weights
-#' \item window : A window for similarities computations; override cross-validation
+#' \item window: A window for similarities computations; override cross-validation
#' window estimation.

#' The method is summarized as follows:
#' \enumerate{
-#' \item Determine N (=20) recent days without missing values, and followed by a
-#' tomorrow also without missing values.
+#' \item Determine N (=20) recent days without missing values, and preceded by a
+#' curve also without missing values.
#' \item Optimize the window parameters (if relevant) on the N chosen days.
#' \item Considering the optimized window, compute the neighbors (with locality
#' constraint or not), compute their similarities -- using a gaussian kernel if
