#' Local linear weights.
#'
#' Computes local linear weights based on Kernel smoothing.
#'
#' Possible options for argument window are "gaussian", "epanechnikov",
#' "tricube", "boxcar", "triangular", "quartic" or "cosine".
#'
#' @param x Covariate values for obtaining estimates for the conditional
#' probabilities. If missing, unconditioned probabilities will be computed.
#' @param kernel A character string specifying the desired kernel. See details
#' below for possible options. Defaults to "gaussian" where the gaussian
#' density kernel will be used.
#' @param bw A single numeric value to compute a kernel density bandwidth.
#' @param t1 Covariate value to compute the weight at.
#' @return A vector with local linear weights.
