#' The SunBai Weighted Transactions Data Set
#' 
#' A small example database for weighted association rule mining provided as an
#' object of class [transactions].
#' 
#' The data set contains the example database described in the paper by K. Sun
#' and F.Bai for illustration of the concepts of weighted association rule
#' mining. `weight` stored as transaction information denotes the
#' transaction weights obtained using the HITS algorithm.
#' 
#' @name SunBai
#' @family weighted association mining functions
#' @aliases SunBai sunbai
#' @format Object of class [transactions] with `r data(SunBai); nrow(SunBai)` transactions and `r data(SunBai); ncol(SunBai)` items. Weights are stored as transaction information.
