课程 9（共 10 门，Specialization Data Science）

A data product is the production output from a statistical analysis. Data products automate complex analysis tasks or use technology to expand the utility of a data informed model, algorithm or inference. This course covers the basics of creating data products using Shiny, R packages, and interactive graphics. The course will focus on the statistical fundamentals of creating a data product that can be used to tell a story about data to a mass audience.

Okay, so here's the slide we're at, in case you're keeping score, now we're just

going to go through and start doing this code demonstration of how to do this.

So, the next couple of slides actually just talk about doing this.

So, instead of going through the slides, I'm just going to show you in our studio.

It's worth noting that we actually practice what we preach, and

here is our slides for this class written in R Markdown.

But, so here is the RMD file for the class, but

we're going to follow through the notes and create a new presentation.

So look what it says, it says, File> New File> R Markdown.

Okay, so you could just do that by Alt+F

> F > R Markdown, that is M.

And then look here, I'm going to click on Presentation Title.

I'm going to call it My Fancy Presentation and the Author is me.

And then you have different outputs.

So this has a different presentation style.

I'm just going to stick with ioslides right now, okay?

And then if you want PDF this requires, we'll go through this later, but

it requires MiKTeX being setup on Windows which is a variant.

MacTeX on OS X, and then TeX Live or something like that on Linux.

So each of these is pretty easy to install, but they tend to be kind of big.

We'll cover that later on in the lecture.

So right now let's just stick with the default, which is ioslides,

kind of a format that was created I think from

one of these Google presentations at one point.

Okay, so there you see it's Untitled1, and

that's the name of the file that contains the R Markdown commands.

But right now,

we're just going to compile it once, and see what it looks like.

So if you click here and say Knit the current document, or

it also gives you the command Ctrl+Shift+K, there we go.

R_Markdown, let me name it a separate R_Markdown,

I'll name it briansSlides, okay?

There its goes.

It runs it, and there it is.

My Fancy Presentation.

Okay.

So homework number one, just go through this, create a new presentation,

a new template presentation, compile it once and

then let's move on from there and fill it up with some content.
