In lf-araujo/sempsychiatry:

#' Function that appends descriptive stats with describe() 
# ' into a file, it does not overwrite previous information. 
#' 
#'
#' Useful in cases where one is working with a large number of
#' variables and needs to perform that several times to print
#' a report.
#' Originally from a question on SO: http://stackoverflow.com/a/43490045/4417072

#' @param vars = variables to be described
#' @param filename = directory path
#' @export
