What is RStudio and Why Should You Download It? | R Tutorial 1.1 | MarinStatsLectures


hi I’m Mike Marin and in this video we’re
going to talk about the difference between R and RStudio. I am getting asked a lot do i need to download and install Rstudio? well, my answer to that would be no! but should you install RStudio? definitely! so what is RStudio? it’s a
free, open-source, integrated development environment or IDE for R: the
statistical programming language. So what does that mean? well basically RStudio helps keep R
bit more organized and it also adds a lot more functionality mainly through
menus; but instead of me saying a bunch of words let’s take a look at R and
then we’ll take a look at RStudio if If we open up R, we can see the console
here: now let’s create a vector X that’s using the numbers 1 to 5; let’s also create
a vector Y that’s the number 6 to 10, and and let’s make a plot of Y versus X. You can see here that the plot pops up in a separate window mine is a bit too large by default and I
would need to resize it in order to have the plot like a little bit nicer also if we want to know what’s in R’s working memory we have to ask for this; we can do
so using the LS command and this lets us know that R see these objects X and Y
in its memory we can see up here that R does have some menu options although
if you take a look and scroll through these you’ll notice that they are pretty
limited Now let’s take a quick look at RStudio so we can go here and open up
RStudio, you can see the console here along with a few other windows; again
let’s create a vector X that’s the numbers 1 to 5 and let’s create another
vector Y that are the numbers 6 to 10 First you can note that we can see what’s in R’s working memory up here now if we take a look at a plot of X versus Y you
can see that appears here in this window if we want to save the plot we can click
on this export tab here and then we can save as an image and here we can see
there’s lots of different options for the file type we can save as we can also
change the height or the width of the plot through here we
can also do this manually if we’d like here’s the file name we’re going to give
it the directory of where we’d like to save the plot so let’s just cancel this. Importing data into R also becomes easier while you can still import data
using commands like the read.table command you can also import data using
the import dataset tab here we can select from a local file that means it’s
saved on our computer and then using these menus we can select the dataset
we’d like here we will load in the lung cap data and you can see here is the name
we’re going to give to our dataset in R we also get a preview down here of
what the data is going to look like and once we import this dataset you’ll see
it pops up here and we get a data view and we can play around with the data a bit
to look at it here for example if we’d like to be sorted by lowest to highest
lung capacities or highest to lowest lung capacities, so this can give us a
quick view of our data; we can also easily create and manage scripts within
RStudio; if you go here to file and then new file, and new R script; so let’s
create and submit a few new commands here. I’m going to create a new variable
and we’re going to create Z that are the numbers 11 to 15 and then we’re
going to add up X, Y & Z; so will sum X, Y & Z and let’s submit those commands let’s submit that here we’re going to
create that new vector X and then we’re going to sum X,Y,Z; and then we could
of course go ahead and save this file and this is going to allow us to save
that script so that we can reproduce our analysis on any given day; you can of
course work with a script directly in R and not RStudio but working this
way within RStudio is a lot simpler and more user-friendly. you can also see
here if you create a new file in R MarkDown, what markdown does is it allows you
to embed R code and R output directly into documents, slides, PDF documents HTML ,word document, and many more you can also see under the menu here you
have this create new project; now what this does is allows you to manage all of
your files and output related to a project in one spot. Now I’ll leave it to
you to explore more of the menu options that are built into RStudio. the point
of what I’ve been trying to show you is that while RStudio is not absolutely
necessary it makes the user experience of working
within the R programming language much much nicer! to me it’s a no-brainer: if
you’re going to work with the R programming language work within the RStudio environment, you’ll be happy that you did Thanks for watching this video
and to learn how to code in R follow along with our series of R tutorials
designed specifically for the beginner who is new to the R software.

  1. I still don't get it why some people still use R, even knowing all the advantages of RStudio.
    Great video, by the way!

  2. Hi Mike
    Can you post more videos on poisson regression model in R, and how to use it to estimate count or rate, something to fit up to intermediate level users . I'm afraid this was not well explored in SPPH 500, like linear or binomial models, at least to me.
    Thank

  3. Hi Mike,
    I've tried to use R in the past, but was to complicated for me, I must admit. Can you recommend me a good beginner's book? Starting really from basics.

  4. datatable is faster package why don't you make a video on it. It is more popular and it is much better

    I mostly work on HUGE datasets. like around 1 or 2 GB data sometimes more than that

    I always have to go to ms access to correct the data.can you reply how to work on data larger than RAM. is there any turnaround.

    BIG data is all I need.

    Please any suggestion would help.

    Please do reply

  5. Hi Mike, first of all, your videos are a great help for a beginner like me! Thank you for posting them! Now, I had a very specific question. Before I dwell further into R, I wanted to know if one can export interactive visuals for the end user, say for instance, the way one can do in Tableau. If I'm providing data visualization to a client of mine I currently have him/her download Tableau reader to see the results and let him/her interact with those. Not only that he/she can interact, Tableau reader is also very clean. But with R, I see codes on the left all the time. Is something interactive plus clean possible with R for the end client? Thanks in advance … 🙂

  6. Hey 🙂 Awesome tutorial 🙂 And good material for programmers. Thanks for it.

    I am the administrator of Facebook I Love Programming(https://fb.com/ilp2013) page and have an offer for you 🙂 And if you don't mind I'll send it to you via email( just let me know your email 😀 )
