##============ Sink warnings and errors to a file ==============
## use the sink() function to wrap all code within it.
##==============================================================
zz = file('warnings_and_errors.txt')
sink(zz)
sink(zz, type = 'message')

  ##============== load packages ===============================
  library(getopt)
  library(rmarkdown)
  library(htmltools)
  library(dplyr)
  library(Rsubread)
  library(DT)
  ##============================================================

  ##---------below is the code for rendering .Rmd templates-----

  ##=============STEP 1: handle command line arguments==========
  ##
  ##============================================================
  # column 1: the long flag name
  # column 2: the short flag alias. A SINGLE character string
  # column 3: argument mask
  #           0: no argument
  #           1: argument required
  #           2: argument is optional
  # column 4: date type to which the flag's argument shall be cast.
  #           possible values: logical, integer, double, complex, character.
  #-------------------------------------------------------------
  #++++++++++++++++++++ Best practice ++++++++++++++++++++++++++
  # 1. short flag alias should match the flag in the command section in the XML file.
  # 2. long flag name can be any legal R variable names
  # 3. two names in args_list can have common string but one name should not be a part of another name.
  #    for example, one name is "ECHO", if another name is "ECHO_XXX", it will cause problems.
  #+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
