cbind Function in R (Example)

This article explains how to column bind a data frame and a vector with the cbind function in the R programming language.

Example Data

In this example, we use the following data frame:

my_data <- data.frame(x1 = 1:5,             # Create first data frame
                      x2 = letters[1:5])
my_data
# x1 x2
#  1  a
#  2  b
#  3  c
#  4  d
#  5  e

We also use the following vector:

my_vec <- c(9, 1, 8, 2, 5)                  # Create vector
my_vec
# 9 1 8 2 5

Note that the number of rows of our data frame and the length of our vector needs to be the same.

Application of cbind Function in R

We can combine our data frame and our vector by column with the cbind function as shown below:

combined_data <- cbind(my_data, my_vec)     # Apply cbind function
combined_data
#  x1 x2 my_vec
#   1  a      9
#   2  b      1
#   3  c      8
#   4  d      2
#   5  e      5
