Extract Column of dplyr Tibble in R (Example)


This article shows how to extract a certain tibble column as vector in R.

The article will consist of the following contents:

Let’s dive right in:


Creation of Example Data

If we want to work with tibbles, we first need to install and load the dplyr package in R:

install.packages("dplyr")                # Install dplyr package
library("dplyr")                         # Load dplyr package

Now, we can create an example tibble as shown below:

data <- data.frame(x1 = 1:5,             # Create example tibble
                   x2 = letters[1:5],
                   x3 = 1)
data <- as_tibble(data)
data                                     # Print example tibble
# # A tibble: 5 x 3
# x1    x2       x3
# <int> <fct> <dbl>
#     1 a         1
#     2 b         1
#     3 c         1
#     4 d         1
#     5 e         1

Our example tibble contains of three columns and five rows.


Example: Extract Column from tbl

If we want to select a specific column of our tibble and convert it to a vector, we can use the pull function:

x1 <- data %>% pull(x1)                  # Extract column from tibble
x1                                       # Print column to console
# 1 2 3 4 5

As you can see based on the RStudio console output, we extracted the column x1 from our tibble and created a new vector with the name x1.
