Create Data Frame from Vectors in R (Example)

In this R tutorial you’ll learn how to construct a data frame from vectors.

Sound good? Let’s start right away.

Creating Example Vectors

The first step is to define some example vectors:

x1 <- 1:5                         # Create first example vector
x1                                # Print first example vector
# [1] 1 2 3 4 5

x2 <- letters[1:5]                # Create second example vector
x2                                # Print second example vector
# [1] "a" "b" "c" "d" "e"

x3 <- c(4, 1, 7, 7, 5)            # Create third example vector
x3                                # Print third example vector
# [1] 4 1 7 7 5

As you can see based on the previous R codes, we have created three different vector objects called x1, x2, and x3.

Let’s combine these vectors in a single data set!

Example: Construct Data Frame from Vectors Using data.frame() Function

This example demonstrates how to convert multiple vectors to a data frame in the R programming language.

To accomplish this, we can apply the data.frame function as shown below. Within the data.frame function, we have to specify the names of the vector objects that we want to merge.

data <- data.frame(x1, x2, x3)    # Create data frame
data                              # Print data frame

Have a look at the previous table: It shows our three vectors unified in a data frame.
