 We will talk about how to create and style PowerPoint presentation slides using our Matdown and my new package PPTS templates, which will take care of a lot of the styling and formatting. So you're at work, you're doing some analysis, you did something cool and you need to share it with someone else. This is very common workflow for most of us, as in the end of the day, analysis or result doesn't mean anything unless we tend to show it to someone else. And you want to make sure that you're sharing it in a way where we keep the reproducibility. So we will turn to some of our common slide creation tools, Swingian, Reveal.js, Beamer, IOSlides. And a lot of these libraries work really well for presentation, but it can be difficult to share and collaborate with collaborators that are not as well versed in R, since they are a little bit wider, a little bit harder to handle, and with that the whole HTML slide format. What would be really nice if we were able to keep all the power from R and reproducibility, but would be able to output PowerPoint presentation slides, because they are by far the most common presentation software out there. And most everybody have some familiarity of how to use and interact with it. So there's three main ways to create a PowerPoint presentation from R. We can use just the standard arm-up-down package, using pan-dot as a bad end. We can use the office-down and the office-up-package. The office-down and office-up-package provides a lot of flexibility with what it can do, but there are quite a lot more work to do it into, and this is why I would only be focusing on the arm-up-down route. So what can we do without going into any of these extra packages? So the PowerPoint presentation output format is a very simple format we can use, and it gives us four different types of slides. So we have the title slide, with the title and content slide, which is the main slide you'll be using. It's the one with the bit area where it protects off it just. There's the session error, which is like the intermediate section one you can use to divide up your presentation into sections. And then we have a class of two, content slide layout with a left and a right-hand side. Let me just show you what they actually look like. So we'll start our PowerPoint presentation with a YAML file. Here's how we specify the output to be a PowerPoint presentation. And we see that the first slide we see will be our title slide, and the title slide is specified with what information we have in the YAML. So we see we have a title, we have all for an update, and these are placed in the PowerPoint presentation. We can also use standard markdown features, such as links and making things bold. It's important to note right here that we used section two header to denote new slide. So every time we're using this double pound symbol, this will denote our next slide. And we can use other features such as bulleted lists. So most of the standard markdown functionality will work inside these PowerPoint presentation slides. Our section header will be a level one header, and this will be a differently styled slide that will only contain this section header right here. So we retain that anything else that is from our markdown. This is the only thing we can do. Our title and content slide is what I think would be your most used ones. This one we've seen a couple times before. We can also add in plots or tables. Anything non-interactive. It's important to note that it can only take one thing. So if you have something that includes text and some kind of element that is a plot or a table, it will be pushed down to the next one. If you want to do the two-toned one, which is like a Ptolema one, it has a left hand side and a right hand side. We have to use this pain.tolum specification to see if the one on the left or the tolerance and it would then place things in these left and right hand side. So we saw a couple of things and there's a couple of different problems. One of them is the slides we saw were fairly plain. Our black and white wasn't much going on and we also saw that we were limited to our more retangular slide format. And additionally, we saw that all the fitters didn't quite fit in the slides as much as they maybe could have been. So this is some of the problems that the PPTH template's practice will try to solve when you install it. You'll get a couple of things. You will get a studio add-in that when used will insert the pain.tolum. So you don't have to remember how many there are. You just use the add-in, you plug it right in. It also includes a couple of templates that show you how to use the different features. And my hope is that you can use those templates and modify them to your corporate theme or whatever theme you like and be able to take full advantage of everything with minimal changes on your part. So this has a much lengthy document showcasing a lot of different things. But this is like the beginning and the main part of it. What you see at the top right here, we have a new reference document. So it includes another PowerPoint presentation file where we have changed the styling of it. And we're telling PowerPoint presentation, hey, use this as a reference of how to style. And then we're loading in PPTH template. And what this one does is pulling out the sizes of the different content areas and saving those as option templates. But this means that now when we move forward, every time we're putting in a plot, we can use this options labels argument in our chunk to say full left and right. And it will make sure that the output of all your plots will fit perfectly inside the template. So now using this template, we can see that our title slide has done a little update. We even added other fancy elements of this line for small gradient in it. We see there's a wider format. And we see that all the content is the same as before, but the styling has been modestly improved. See different ones. And notice how the plots now fill the area perfectly. And this is also just a showcase that when you're doing a two-tonsent layout, you don't need to do a 50-50 split. Everything will just follow our template. So I'd like to thank you very much for listening along. The repository will also include a video of how to format these PowerPoint presentation templates. Thank you.
