#' Create data for 2 samples/groups
#'
#' This creates a dataset with 1000 participants to be used with the main function.
#' \code{\link{rate.statistics2}}. It can be run with its defaults sdt.rmcs() or by specifying parameters.
#'
#'
#' @param tot.signal A number - The total number of signals i.e. blue dots that have to be detected Default = 85
#' @param tot.lure A number - The total number of lures i.e. number green dots that should not be responded to, Default = 100
#' @param min.hits A number - Minimum ammount of hits for group 1. Dafalt to 0.7
#' @param min.cr A number - Minimum ammount of correct rejections for group 1. Dafalt to 0.8
#' @param min.hits2 A number - Minimum ammount of hits for group 2. Dafalt to 0.3
#' @param min.cr2 A number - Minimum ammount of correct rejections for group 2. Dafalt to 0.3

#' A data table with the following columns
#' \item{hits}{total number of hits per participant randomly chosen between tot.signal and the minimum proportion hits specified}

#' \item{miss}{total number of misses per participant - left from the total signals after removing hits}
#' \item{falarm}{total number of false alarms per participant - left from the total lures after removing correct rejections}
#' \item{hits2}{total number of hits per participant for group 2 randomly chosen between tot.signal and the minimum proportion hits specified}
#' \item{corRej2}{total number of correct rejection per participant for group 2 randomly chosen between tot.lure and the minimum proportion critical rejections specified}
