Replicate Column with & Add to Data Frame with New Name in R (Example Code)

In this tutorial, I’ll show how to duplicate a variable in a data frame in the R programming language.

Example Data

data(iris)                        # Example data
head(iris)                        # Display head of example data
#   Sepal.Length Sepal.Width Petal.Length Petal.Width Species
# 1          5.1         3.5          1.4         0.2  setosa
# 2          4.9         3.0          1.4         0.2  setosa
# 3          4.7         3.2          1.3         0.2  setosa
# 4          4.6         3.1          1.5         0.2  setosa
# 5          5.0         3.6          1.4         0.2  setosa
# 6          5.4         3.9          1.7         0.4  setosa

Example: Add Duplicate of Column to Data Frame

iris$Species_2 <- iris$Species    # Replicate variable
head(iris)                        # Display head of updated data
#   Sepal.Length Sepal.Width Petal.Length Petal.Width Species Species_2
# 1          5.1         3.5          1.4         0.2  setosa    setosa
# 2          4.9         3.0          1.4         0.2  setosa    setosa
# 3          4.7         3.2          1.3         0.2  setosa    setosa
# 4          4.6         3.1          1.5         0.2  setosa    setosa
# 5          5.0         3.6          1.4         0.2  setosa    setosa
# 6          5.4         3.9          1.7         0.4  setosa    setosa
