►In this R video tutorial, we will learn to use read.table function (which reads a file in table format and creates a data frame from it, with cases corresponding to lines and variables to fields in the file), and some of the arguments such as header argument and sep argument.
►We will learn to use file.choose function to choose a file interactively
►We will discuss how to use Menu options in RStudio to import data into R
►and we will also learn how to check the imported data to make sure it was imported correctly into R using the dim function to retrieve dimension of an object and specify the number of rows and columns of the imported data, the head function in R (head() function), which returns the first or last parts of a vector, matrix, table, data frame and will let us see the first several rows of the data, the tail function in R (tail() function) to see the last several rows of the data in R, the double square brackets in R to subset data (brackets lets you select or subset data from a vector, matrix, array, list or data frame) , and the names function in R to get the names of an object in R.

In this video tutorial, we will learn to use various functions and arguments in R and menu options in Rstudio to read the data into R. You will also get familiar with functions that would help to verify if the data was imported correctly into R (e.g number of rows and columns, names of the objects, etc). Practice with this free dataset: (https://statslectures.com/r-scripts-datasets); After learning how to import data into R, watch our next video to learn how to export data out of R (csv, txt, and other formats) (https://bit.ly/2PWS84w); Like to support us?

The best tutorials I have found lately!!!! Thank you, Sir. I truly appreciate the effort you put into making these tutorial videos. I have a small inquiry about finding the dataset you used in your videos, as the provided link in the description is not working! Is there any other way I can get that dataset for practice?
now is 2024 and this 11 years old video are the best tutorial video
Please share the dataset, the link in the description doesn't work
Kindly share the datasets
Great tutorials!! I can't access the data
10 years later these are still the best R tutorials ever so far. Thank you very much!
Thanks!
This dude is saving my life with his clear and simple explanations
8 years later these are still the best R tutorials ever. Thank you very much!
OMG, five mins of this video is 100 times better than my prof 2 hrs lecture
Thank you.
We UoPeople students love your videos. It is super helpful ^^ .
Thanks
Great videos and great tutorial. I was struggling to understand these concepts but now I am feeling relaxxxxxxxed
great video! wish I'd had this a week ago when my columns weren't separating.
Hi Mike, This is a great resource. After importing and attaching, I am getting error message in many commands e.g.
> head(LungCapData)
returns error as follows
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) :
namespace ‘rlang’ 0.4.5 is already loaded, but >= 0.4.7 is required
I am getting similar error in > LungCapData[5:10, ] command.
Could you please let me know what could be the problem. This error persists even after changing character variables using 'as.factor' function
How did you find the path to your file?
hi i am getting junk text in front of my dataname when i print data for example if the first header is qualification it is showing i… qualification can u help. thanks
Great tutorial
super interesante pero estoy con problemas para bajar un archivo outside the worl and zipedd
You didn’t taught us to create data frame?
Fantastic tutorial. Do you also have videos on a beginner project in R? To better hone one’s skill.
What if I need to separate by more than 3 separators? How can that be done? Levels and sublevels.
Cool and amazing way to teach R ……👍👌🙏🙏🙏
not too shabby

i wish i saw this tutorial earlier..
Thanks man. You make the world a better place by lifting us all up. this is bigger than youtube tutorials, you are actually benifitting lives in so many ways

Hi, I was wondering if you have a video on working with Panel Data in R and how to correctly import it from Excel?
how i fixed this permission denied message
Hi! i am getting the error message permission denied while running this command read.table
Thank you for the sharing your knowledge in a very simple and easy way to learn.
Sir can I get ur lungcapdata.txt file?So I can practice perfectly.. thanks sir
3:30 is where it shows data import from a text file.
thank you sir, easy to understand and please add more complicated programming videos based on R
