Situation: I’m running a contest and I have an introduction slide for each participant in a separate deck. I want the slides to show up in the random order from when it was created. More generically, you have a Powerpoint deck and you want the whole thing resorted into a random order. Here is a link to an article that provides instructions and code to do that.
Here is a Powerpoint file with the code embedded as an example.
Note that this will shuffle allthe slides in a file.
This will work using the current version of Powerpoint on both Mac and Windows (2016).
This method will randomize your slides without having duplicates.
If you have a bunch of slides and you want them to appear in a random sequence but don’t care if there are repeats, check out this article.
Here is a Powerpoint file with the macro already created.

Besides the XML package, Omega Project for Statistical computing has a number of other R-Project packages that look very interesting, like KML, Python, and WordPress packages.
Code example of how to get the current directory, change directories, and set the output to someplace specific – designed to work on both windows and unix.
# Finds the directory that a program was run from, change the directory
# and creates an output file within a subdirectory. This code is designed
# to run on both mac and windows.
# what is the current working directory? notice the difference when running
# from unix/mac verses windows
# change the current working directory. use forward slash regardless of unix
# or windows
# create a file in a subdirectory from the current working directory
# this method makes the results operating system agnostic
# each entry in the parameters is the next directory level, ending with the
# file name os.path.join inserts the appropriate separators
file_path = os.path.join(wd,"xml","output.xml")
# file is now open as 'f'
