+#' @title dataFrameFillDS
+#' @description An assign function called by the clientside ds.dataFrameFill function.
+#' @details This function checks if each study has all the variables compared to the other studies
+#' in the analysis. If a study does not have some of the variables, the function generates those
+#' variables as vectors of missing values and combines them as columns to the input data frame. 
+#' Then, the "complete" in terms of the columns dataframe is saved in each server with a name
+#' specified by the argument \code{newobj} on the clientside. 
+#' @param df.name a character string representing the name of the input data frame that will be
+#' filled with extra columns with missing values if a number of variables is missing from it
+#' compared to the data frames of the other studies used in the analysis.
+#' @param allNames.transmit unique names of all the variables that are included in the input 
+#' data frames from all the used datasources. 
+#' @return Nothing is returned to the client. The generated object is written to the serverside.
