#' @title Call selected functions from the package Hmisc
#' @description At the moment only the function 'rcorrcens' is implemented. Due to implementation specifics the 'data' argument
#' for this function is mandatory (and is specified as a character, the name of a data frame) and the 'formula' argument must be set as a character (enclosed in quotes)
#' @param func a character, the name of the function to call
#' @param ... further arguments to be passed to the function (see the documentation of the Hmisc package).
#' @param newobj a character name of the new object to be created on the nodes if this is an assign function, ignored otherwise.
#' @param async a logical, see datashield.aggregate

#' @param  datasources a list of opal objects obtained after logging into the opal servers (see datashield.login)
#'
#' @export
#'
