#' @title Predictions from a functional gls object
#'
#' @description The predictions for the functional generalized least squares fitted linear
#' model represented by \code{object} are obtained at the covariate values
#' defined in \code{newx}.
#'
#' @aliases predict.fregre.gls predict.fregre.igls
#'
#' @param object \code{fregre.gls} object.
#' @param newx An optional data list in which to look for
#' variables with which to predict. If omitted, the fitted values are used.
#' List of new explanatory data.
#' @param type Type of prediction (response or model term).
#' @param se.fit =TRUE (not default) standard error estimates are returned for
#' each prediction.
#' @param scale Scale parameter for std.err. calculation.
#' @param df Degrees of freedom for scale.
#' @param interval Type of interval calculation.
# @param level Tolerance/confidence level.
#' @param weights variance weights for prediction. This can be a numeric vector
#' or a one-sided model formula. In the latter case, it is interpreted as an
#' expression evaluated in newdata
#' @param pred.var the variance(s) for future observations to be assumed for
#' prediction intervals. See \code{link{predict.lm}} for more details.
#' @param data Data frame with the time or spatinal index
#' @param n.ahead number of steps ahead at which to predict.
#' @param \dots Further arguments passed to or from other methods.
#'
#' @return a vector with the predicted values.

#' @title Predictions from a functional gls object
#'
#' @description The predictions for the functional generalized least squares fitted linear
#' model represented by \code{object} are obtained at the covariate values
#' defined in \code{newx}.
#'
#' @aliases predict.fregre.gls predict.fregre.igls
#'
#' @param object \code{fregre.gls} object.
#' @param newx An optional data list in which to look for
#' variables with which to predict. If omitted, the fitted values are used.
#' List of new explanatory data.
#' @param type Type of prediction (response or model term).
#' @param se.fit =TRUE (not default) standard error estimates are returned for
#' each prediction.
#' @param scale Scale parameter for std.err. calculation.
#' @param df Degrees of freedom for scale.
#' @param interval Type of interval calculation.
# @param level Tolerance/confidence level.
#' @param weights variance weights for prediction. This can be a numeric vector
#' or a one-sided model formula. In the latter case, it is interpreted as an
#' expression evaluated in newdata
#' @param pred.var the variance(s) for future observations to be assumed for
#' prediction intervals. See \code{link{predict.lm}} for more details.
#' @param data Data frame with the time or spatinal index
#' @param n.ahead number of steps ahead at which to predict.
#' @param \dots Further arguments passed to or from other methods.
#'
#' @return a vector with the predicted values.
