6 ##============ Sink warnings and errors to a file ==============
|
|
|
7 ## use the sink() function to wrap all code within it.

8 ##==============================================================

14 ##=============STEP 1: handle command line arguments==========
|
|
|
15 ##
|
|
|
16 ##============================================================
|
|
|
17 # column 1: the long flag name
|
|
|
18 # column 2: the short flag alias. A SINGLE character string
|
|
|
19 # column 3: argument mask
|
|
|
20 # 0: no argument
|
|
|
21 # 1: argument required
|
|
|
22 # 2: argument is optional
|
|
|
23 # column 4: date type to which the flag's argument shall be cast.
|
|
|
24 # possible values: logical, integer, double, complex, character.
|
|
|
25 #-------------------------------------------------------------
|
|
|
26 #++++++++++++++++++++ Best practice ++++++++++++++++++++++++++
|
|
|
27 # 1. short flag alias should match the flag in the command section in the XML file.
|
|
|
28 # 2. long flag name can be any legal R variable names
|
|
|
29 # 3. two names in args_list can have common string but one name should not be a part of another name.
|
|
|
30 # for example, one name is "ECHO", if another name is "ECHO_XXX", it will cause problems.
|
|
|
31 #+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

59 ##===========================================================

77 ##===========================================================
