#' Prediction of logP based on the atom-type method called XLogP.
#'
#' @param molecules Parsed molucule object.
#' @param silent Logical. Whether the calculating process
#' should be shown or not, default is \code{TRUE}.
#'
#' @return A data frame, each row represents one of the molecules,
#' each column represents one feature.
#' This function returns one column named \code{XLogP}.
