An Introduction to R - A Brief Tutorial for R {Software for Statistical Analysis}

[@jasonjestila101]

It is rare to find a youtube video that is exactly what you need. Very concise. Well done sir, well done.

[@katepeng3774]

Thank you so much for guidance. Your instruction helps me overcome the fear of opening up this software!

[@chittasandeep]

+Kate Peng me too.

[@rachittyagiyoutube]

Kate.. Now u are perfect i guess

[@sujankafle1579]

Its the basic which most people often tend to ignore. A video from 10 years old is still relevant and helpful.

[@chriscollins5320]

Excellent intro video. Topics were perfectly organized and executed for quick and fast understanding. Great examples as well.

[@NateSwaggDeezy]

thx. FYI best way to nav xls is hold Ctrl + press arrow key (to jump) or hold Ctrl + Shift + press arrow key (to select range); can then press another arrow key to select multidimensional array/range (matrix/table/relation). Ctrl + L to make a list (table format)

[@huttumama2110]

Its Now 2019; everyone use R-Studio; But your effort was very impressive. Specially fix() function helps me a lot. Thanks!!!!

[@patriciarono6457]

You are an awesome teacher. I have understood heaps of stuff that i couldn't in two days.awesome

[@aibocoqui]

Excellent class. As former user of SPSS and with the advent of R with all its applications this video is a great start. I'm reading R for Dummies and it also mentions RStudio as a helpful tool. Nonetheless its great to start learning from scratch so that you can appreciate the usefulness of RStudio.

Two Alternatives or Tips for .sav files: a) Google "spss .sav file, read into r" - there are a couple examples out there. b) Save the part of the .sav file you're interested in as a .CSV (which is what I see a lot of psych grad students do)

[@Pywel_drwg]

Perfect speaking pace, really helped

[@economicurtis]

Wonderful, thanking you Prash Chan. The goal was to make the very basics easy to get through so you can more on to more interesting thing with R!

[@vimsen2221]

Learnt a lot in this 16 min tutorial.

[@economicurtis]

I got a comment to this video (that's since been removed) >>"how do you insert a .sav file?" I think .sav files are used with the SPSS stats program (popular in Psych research, among other areas I'm sure). To read these files into r (which don't immediately recognize .sav files), you'll need the "read.spss()" function from the foreign library (type the line "library(foreign)") and the "spss.get()" function from the Hmisc package (click "Packages" >> "Install Package(s)" >> Hmisc) I

Hi Curtis and thank you, thank you, and thank you for these great videos. I appreciate your dedication to providing these valued videos which have assisted greatly. Chris Lira

[@sakamuk]

This video was really informative. I am familiar with Eviews, SPSS and STATA but I never learned how to use R....so thanks loads :)

[@easydatascience2508]

Amazing course !!!

[@mapuaharry]

Very helpful ;). I wish the audio was much louder.

[@allisonbauser8021]

Good job. Brand new to R as well as computer language. I hope to learn it by myself. Thanks.

[@givemethisdamnname]

thank you...still helping, years later!

[@economicurtis]

Thanks for your thanks. I'll update these one day. It's amazing how little help there is for non-programmers that still need to learn R

[@givemethisdamnname]

No kidding! :-)

I love your simple way to explain!! excellent

[@iamsuperfritz]

hey everyone, the file name is NHIS_2007_data.csv, not nhisdata.txt as he has it in the video. You will get an error if you try to download the file and follow his directions exactly

[@economicurtis]

I noticed this too. How to you fix it?

[@niazmorshed5737]

Thank you

[@groover8191]

Lovely introduction. I look forward to diving into R.

[@christinebishop9020]

this was the most easy to follow explanation. Do you have any other step by step guides using more complicated R functions!

[@mdmgeek]

Thank You so much for this video. Really helpful getting started. Loving R after doing this lab.

[@maxjohn6012]

Thanks for this. I've learned a bit of Python for my masters, have to learn R for my PhD. Python looks SOOO much nicer lol, but thanks for uploading something simple about csvs lol, that's a nice introduction :)

[@Heyimin995]

How many months you took to master r ???

[@DraRed73]

That was worth watching. Thanks for sharing your knowledge.

[@economicurtis]

Not sure what PCoA is (perhaps Principal coordinates analysis?) Perhaps one day I'll get to this. For now, I have a very simple Intro to Econometrics course I should getting videos ready for. Sorry! Best of luck!

[@admassuk.2419]

Great video. Good job! One question. How can I download 'Beginning.RData' ?

[@economicurtis]

Great point Gubba Banoosh! I don't think a 2-way anova would be appropriate in this context either. Thanks for the feedback!

thank you so much for posting this video! it's extremely helpful!

[@maxineprado770]

Hi. Thank you for this tutorial, i find it very useful. I'm actually new to R and really want to understand how to use this software in dealing with my data. I'm working on abundance and diversity data and I want to save time in coming up with graphs and other outputs instead of using the conventional Excel. Again, thanks a lot!

[@economicurtis]

This is a good way to start. My little video tutorial is pretty old now, I think there are great resources on using R with IDEs like RStudio -- often with topic-specific video tutorials -- you might check out too. Best of luck

[@MrPeetersDaan]

Thanks! I have a question, the excel file I want to import displays not properly in R, with commas in between and not nicely in columns like it should. Now I noticed in your attached file, that you don't make columns in Excel but you seperate everything with a comma.Is this why my data doesn't display well in R? How can I change it ( I have quite a lot of data to import, so I cannot just adjust everything by hand)

[@neethusebastian412]

You mention using NHIS data. Is it possible to import .dat into Rstudio directly . If not what is the other option? I am trying to use NHIS 2013 data. How did you download it in the text file format?

Love your video! Really helpful~

[@razamujahid9123]

what if we want to make a graph to describe relation of two variables? what we need to add further?

[@gaurivishwasrao8151]

Could you upload a video for only for different commands we can use in R?

[@economicurtis]

Thanks! Happy to be of some help!

[@charliespencer794]

Very Helpful! I was wondering, if I am using Treemix to produce graphs, how do I then further analyse these graphs using R? Say I want to plot one population against another - how do I write this command using vectors?

[@economicurtis]

Hi Charlie Spencer. I'd check out a video/resource on R plotting. In particular, check out ggplot2 (it makes pretty plots with fairly easy code.). To help you get started, check out the "line graphs" section here: www.cookbook-r.com/Graphs/Bar_and_line_graphs_(ggplot2)/

[@charliespencer794]

economicurtis Thank you this has been very helpful! Do you have any experience with a software called Treemix as well by any chance?

[@simonxxsunday]

Let's say i would want to create a new variable called "Sum" to sum up the last three rows (in your case: education, height and weight). How would i do that?

[@joeaament]

I am unable to figure out how to download the R software that you have. I downloaded R and only see a console. Am I missing something? I've downloaded the RStudio GUI but I wanted to be able to follow exactly what you're doing in this video. Thanks!

[@economicurtis]

I'm working on an econometrics with R series of videos. But nothing ready yet. I really like GordonAnthonyDavis youtube videos, if you want a recommendation.

[@anhleroy]

Do you know of any examples of using R in conjunction with GIS for statistical analysis?

[@guitashamilele]

massively useful, thank you so much

[@tofilover]

will taking a course in R be suitable for a biology master student with no experience with computers and coding?

[@bolajoko11]

Thanks a bunch. this was of great help

[@economicurtis]

Sorry. I do not (I don't go any geo tagging or anything with maps). But check out r-bloggers (an aggregation of R blogs), they have dozens of articles on GIS with R.

[@LeBadman]

Good thing there is RStudio. :)

[@macacoman]

What is the RStudio?

[@LeBadman]

A program to make it easier to work with R.

[@economicurtis]

macacoman Definitely check it out. I use Rstudio (in particular RStudio Server) every day. It's a free and open source IDE (essentially a better GUI on top of R) for your R workspaces and projects.

[@LeBadman]

Yes, you have many advantages like IntelliSense (which is variable autocompletion), your used variables and objects on the right of your screen, file management and many other useful things.

[@bubbaganoosh6971]

Hi Tung Mai, with 3 observations you can not assess statistical significance, as its not enough data to get any meaningful estimate of variation. a two-way ANOVA is not appropriate...2-way anova would be useful if you had a numeric response (Y) variable and two explanatory (X) variables that are both categorical. it sounds like you have just the one variable, and two-way ANOVA is not at all what you'd want to use!

[@funlandvidoes799]

How did you insert the excel sheet?

[@John_Fx]

My kingdom for an R Intro video that shows doing at least something useful instead of tittering on about the R studio API endlessly.

[@economicurtis]

There is very little information given here. Sounds like you want some sort of two-way anova test.... maybe. But with only three observations I'm not sure you can do much. Best of luck!

[@nicolenachif5471]

Hi, first of all thanks you for the video!!!. I didnt't know anything about this kind of programs and this was very helpful. Secondly, I'm trying to upload an excel file (previusly saved as a csv file) but I can't do it. It appears on R window that there is an error and I have in the file a "magic number" that are letters from the file indeed. I was trying to upload it grabing the file from the folder to the R window and then write on the editor window all the codes that you've put on the video. I don't know what's happening, maybe someone can help me. Thanks you so much.

my teacher said you should put your working diectory in first.. does this matter ?

[@economicurtis]

In general if you're new to something like R, I'd follow your teacher's advice. I too generally set my working directory when I get started (this is done automatically with rstudio when you create a new rstudio "project"). I left it out of here for brevity's sake.
