#' @param table \code{character} Name of the table on the server side that holds the information to be plotted later
#' @param variables \code{character vector} Name of the column(s) of the data frame to include on the boxplot
#' @param group \code{character} (default \code{NULL}) Name of the first grouping variable. 
#' @param group2 \code{character} (default \code{NULL}) Name of the second grouping variable. 
#' @param datasources a list of \code{\link{DSConnection-class}} (default \code{NULL}) objects obtained after login
#'
#' @return Does not return nothing, it creates the table \code{"boxPlotRawData"} on the server arranged to be passed to the
