My name is Colton Ogden, and today I am joined for the first time by--

tell us a little about what would you do here

So I am a master student studying bioinformatics.

I'm also a special student in computer science,

and I actually work at HarvardX, so if you guys

are familiar with the online learning platforms of Harvard, that's

one of the offices that has really good resources.

didn't I-- I met you in the spring, I think.

You came to the fair for the Supreme Court.

COLTON OGDEN: And I think you were talking

And what are you going to talk about today?

ANDY CHEN: Well today we're going to talk about a programming

language called R, and one of the things you

can do in it which includes biostatistics.

ANDY CHEN: Cole, you might ask me what is biostatistics?

ANDY CHEN: So it's really statistics in the field of like biological data.

But a lot of people use it in the context of epidemiology,

as opposed to more like molecular biology kind of things.

And that's actually what we're going to be dealing with today.

COLTON OGDEN: That's diagnosing diseases, right?

ANDY CHEN: Epidemiology is sort of the study

and the practice of response to the spread of diseases.

I'm not an expert on biology or biostats.

We have a lot of people in the chat that have joined us,

and were talking before we started a little bit in advance.

Thank you very much to everybody who's joined.

There's a new regular, Asley, Newanda33333, belacures,

Let me make sure I didn't miss anybody up above that.

[INAUDIBLE] and fatma, thank you for joining

Really curious about about this one says m.kloppenburg.

This is the first time we've had anything kind of statistics

COLTON OGDEN: Python's obviously a language

that's very often used in bio or in stats, generally speaking.

But R kind of like the language that people I think, maybe most people

associate-- or at least they associate starts with R, and then R also

sort of with stats that end with Python, too.

I don't know anything about R, so I'm actually

very curious to see what it looks like, what the environment looks,

I think we've caught up on all the comments.

Everybody's saying hey Andy, nice to meet you Andy, everybody saying,

so you got a lot of friends in the chat there.

Let's go to your screen here, so we have your screen set up.

Hello everyone, hello friends from all over the world.

So R, like Colton was saying, is one of probably two languages

that are very popular for statistics or data science kind of things,

Today we're going to be looking at R, which let's go to the website.

The first thing we're going to be doing is installing the language itself.

Now notice that we actually are not going

well actually I don't know what I'm running,

but whatever-- on Mac you have to install R the language itself,

which actually I think does have a command line interface.

But we're going to be working in R Studio, which

COLTON OGDEN: Integrated development environment.

ANDY CHEN: Development environment, thank you.

ANDY CHEN: But yeah, so we're going to be installing

R, which is the language itself, as well as R Studio, which
