Let’s imagine that you have an actual dataset containing a collection of columns (“variables” in data terminology) and rows (“observations” in data terminology). For example, maybe your dataset is:
| Name | Age | Favorite Color |
|---|---|---|
| Dean | 12 | Blue |
| Xiao | 18 | Green |
| Sara | 22 | Red |
| Ravi | 21 | Purple |
| Maya | 17 | Blue |
In this case, your dataset has three “variables” (name, age, and favorite color), and five “observations” for each of these variables (corresponding to the values for 5 unique people). You might even recognize this data from the previous chapter: the values in the “Age” column are the values from our age vector and the names correspond to the names that we gave our age vector, along with some extra “Favorite Color” information.
While we could define a separate vector variable in R for each column in our data, such as
Once we started analyzing this data, it would quickly become hard to keep track of which age corresponded to which name, and what their corresponding favorite color is since the variables are each stored in three separate objects. For example, if I look at the color_vec vector by typing its name:
color_vec[1] "blue" "green" "red" "purple" "blue" It isn’t clear whose color preference is whose.
It would be much nicer if we could create a single object containing all three of these variables such that the corresponding values are “aligned” in such a way that it is very clear that “Ravi” has age 21 and favorite color “purple”.
Fortunately, the creators of R share our desires, so they let us store each of our vectors in an object called a “data frame”.
If I already have the columns of my data stored as separate vectors, I can create a data frame using the data.frame() function as follows:
my_data <- data.frame(name = name_vec,
age = age_vec,
color = color_vec)Where the name to the left of the = symbol in my data.frame() arguments defines the corresponding “column name” in my data frame.
Since my_data is an R object, I can view it by typing its name:
my_data name age color
1 Dean 12 blue
2 Xiao 18 green
3 Sara 22 red
4 Ravi 21 purple
5 Maya 17 blueNow our three variables are neatly arranged in rows and columns, where there is one row for each person and one column for each variable and this is all stored in a single variable/object called my_data.
The integer numbers 1, 2, 3, 4, and 5 shown along the left-hand side of the rows are not actually a part of the data object itself (notice that there is no “column name” printed above these integers). These numbers are just visual aids provided by the R console when you print a data frame object to make it a little bit easier to count the rows in the data.
If I ask R what kind of object my_data is, it tells me it’s a “data.frame”.
class(my_data)[1] "data.frame"And I can get a quick summary of what my data frame contains using the str function:
str(my_data)'data.frame': 5 obs. of 3 variables:
$ name : chr "Dean" "Xiao" "Sara" "Ravi" ...
$ age : num 12 18 22 21 17
$ color: chr "blue" "green" "red" "purple" ...In particular, the things that I find helpful in this summary are the number of “obs.” (5) and “variables” (3), and the type/class of each variable shown after its name, which tells me that the name and color columns have a “chr” (character) type, and the age variable has a “num” (numeric) type.
Each column in a data frame can have a different type, but each entry within a single column must be the same type (because each column corresponds to a vector).
There are several techniques for extracting the vectors stored in a data frame. For instance, if I wanted to extract the age column, or specifically, the vector corresponding to the age column, I can write:
my_data$age[1] 12 18 22 21 17or
my_data['age'] age
1 12
2 18
3 22
4 21
5 17These two approaches both extracted the age column, but notice that the output of these two column extraction techniques look a little different.
Can you guess why? Hint: What type/class do you think each output object has? Look at its formatting. Learning to recognize what type each object has based on the way it looks is a really helpful skill.
The output of my_data$age looks is an ordinary vector. I can tell because the values are arranged horizontally, and there is a [1] at the beginning of the output. But this isn’t the case for the output of my_data['age']. The output here looks more like our data frame output (but with only one column).
Indeed, if I ask R to tell me the class of each of these two objects that I have extracted, I learn that the my_data$age object has a “numeric” type (remember that a vector containing numeric values will have a “numeric” type!)
class(my_data$age)[1] "numeric"And I learn that the my_data['age'] object has a “data.frame” type:
class(my_data['age'])[1] "data.frame"Since data frames and vectors have different behaviors, there will be some scenarios where you prefer your extracted column to be a vector, and others where you will prefer your extracted column to be a single-column data frame.
While I occasionally want to extract columns from my data as a vector using one of these techniques, I typically conduct my data analyses and modifications on the data frame object itself. You’ll encounter some sophisticated techniques for working with data frames in the next chapter. But first, I want to show you how to load a dataset that you have saved on your computer into a data frame in R.
5.1 Loading data from external files
To create the my_data data frame object above, I first created the individual vectors, which I then used to define the columns of my data frame within the data.frame() function. Imagine if your data had hundreds of observations/values for each of hundreds of variables. No one wants to manually type their data into R.
More often than not, the data you want to analyze will already live in a file on your computer, such as a .csv file or an Excel spreadsheet. In this section, I will show you how to “load” data from such files into an R data frame.
5.1.1 Loading data from .csv data files
.csv files are one of the simplest data formats. “csv” stands for “comma separated value”. In a .csv file:
Columns are separated by commas
New rows are created by starting a new line
The .csv version of our data above looks like this:
name, age, color
Dean, 12, blue
Xiao, 18, green
Sara, 22, red
Ravi, 21, purple
Maya, 17, blueTo load in a dataset (as a data frame) from a .csv file, we can use the read.csv() function. However, for R to be able to find your file you need to provide a “filepath” argument (as a character/text value) to your csv file.
The file path corresponds to the location where your file lives on your computer relative to where the current R file you are working in is saved. Ideally, you are working in a quarto document. If so, identify where on your computer you have saved your quarto document. If your csv data file lives in the same folder as your quarto document, then you will write
data <- read.csv("filename.csv")where you replace "filename.csv" with the actual file name of your .csv file.
If your .csv data file lives in a data/ subfolder, then you will write
data <- read.csv("data/filename.csv")When you compile a quarto document (which will involve sequentially running all of the code in the code chunks), R automatically searches for any referenced files in the folder where the quarto document is saved.
However, if you run the code in the console, R might not automatically know to look for files in the same folder as your quarto document. To ensure R can locate your files, your console’s working directory needs to match the folder containing your quarto document. The working directory is the folder where your R console looks for files to load (and where it saves any files you create).
All file paths in code that is run in the console are relative to your console’s current working directory, regardless of where your quarto document is saved.
If you open RStudio by directly opening a quarto document or an R script, the working directory is typically set to the folder containing that file. However, if you open your IDE without opening a specific file, the working directory is likely set to your computer’s home folder.
If the console’s working directory doesn’t match the folder where your quarto document or R script is saved (the location of the code you’re running), R won’t be able to find your data files.
Identifying the console’s current working directory
You can see your console’s current working directory by looking at the top of the console. In the image below, the working directory is the “Documents” folder. If you just see ~, then your console’s current working directory is your computer’s home folder.
Changing your console’s working directory
It is recommended that your working directory matches the location of the quarto document you are working in.
You can update your console’s working directory to be the location of your current quarto document in RStudio by choosing “Session > Set Working Directory > To Source File Location”.
Let’s load an actual .csv file. If you are working in a quarto document or an R script on your computer, take note of where you saved it. Then download the following “data” folder containing the “gapminder” dataset and move the data folder to the same location as your current quarto document.
If you are working in a quarto document called “analysis.qmd” then your folder should have the following structure, in which the “data” folder lives in the same place as “analysis.qmd”:
Then, assuming that your console’s working directory matches the location of your quarto document on your computer, you should be able to run the code below to load in the gapminder.csv data file and save it as a data frame object called gapminder:
gapminder <- read.csv(file = "data/gapminder.csv")If you get an error that says "Warning message: In file(file, "rt") : cannot open file 'data/gapminder.csv': No such file or directory", this means that either you did not move the “data” folder containing “gapminder.csv” in the right place, or your console’s working directory is incorrect!
Hopefully you figured out how to tell R to find and load your dataset! If your code above worked, you should then be able to take a look at the gapminder object by typing its name:

In general, you want to avoid printing your entire dataset in your R console or rendered quarto document.
Instead, try printing just the first few (6, to be exact) rows using the head() function:
head(gapminder) country continent year lifeExp pop gdpPercap
1 Afghanistan Asia 1952 28.801 8425333 779.4453
2 Afghanistan Asia 1957 30.332 9240934 820.8530
3 Afghanistan Asia 1962 31.997 10267083 853.1007
4 Afghanistan Asia 1967 34.020 11537966 836.1971
5 Afghanistan Asia 1972 36.088 13079460 739.9811
6 Afghanistan Asia 1977 38.438 14880372 786.1134Now that we are starting to get a handle on our gapminder data frame, let’s talk about the information it contains. The gapminder dataset contains information on life expectancy, population, and GDP per capita for 142 countries every 5 years between 1952 to 2007. Each country has 12 rows in the data, one for each year.

5.2 Attributes of a data frame
Often I find it helpful to print out just the column names of a data frame using the colnames() function:
colnames(gapminder)[1] "country" "continent" "year" "lifeExp" "pop" "gdpPercap"We can also ask things like how many rows our data frame has using the nrow() function:
nrow(gapminder)[1] 1704We can ask how many columns our data frame has using the ncol() function:
ncol(gapminder)[1] 6Or we can ask both how many rows and how many columns our data frame has at the same time using the dim() function:
dim(gapminder)[1] 1704 6We can use our trusty str() function from earlier to take a sneak peek at the “structure” of our data:
str(gapminder)'data.frame': 1704 obs. of 6 variables:
$ country : chr "Afghanistan" "Afghanistan" "Afghanistan" "Afghanistan" ...
$ continent: chr "Asia" "Asia" "Asia" "Asia" ...
$ year : int 1952 1957 1962 1967 1972 1977 1982 1987 1992 1997 ...
$ lifeExp : num 28.8 30.3 32 34 36.1 ...
$ pop : int 8425333 9240934 10267083 11537966 13079460 14880372 12881816 13867957 16317921 22227415 ...
$ gdpPercap: num 779 821 853 836 740 ...And we can use the summary() function to get some statistical summaries (like the minimum, median, mean, maximum, and the quartiles) of each of the numeric columns in our data frame (this summary is fairly useless for character/categorical columns though):
# use summary() to look at a summary of gapminder

Then print out the first 6 rows, the column names, create a summary of the data, and report its dimension.

Loading data from Excel, SPSS, Stata, and files is almost as easy as loading data from .csv files, except that you will need to install some add-on packages to do so. Specifically, to load Excel files, you will need to install the “readxl” package, and to load SPSS, Stata, or SAS files, you’ll need to install the “haven” package.
You’ll learn about installing and loading packages in the next chapter. Click here to learn more about loading data from Excel files and click here to learn more about loading data from SPSS, Stata, and SAS files.
