How to Create a New Data Frame from Existing Data in R (Example Code)

This article explains how to make a data frame from an existing data set in the R programming language.

Example Data

data(iris)                                  # Load example data frame
head(iris)
#   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: Subset Certain Columns from Existing Data Frame

iris_subset <- iris[ , c("Sepal.Length",    # Create data frame from another
                         "Petal.Length",
                         "Species")]
head(iris_subset)
#   Sepal.Length Petal.Length Species
# 1          5.1          1.4  setosa
# 2          4.9          1.4  setosa
# 3          4.7          1.3  setosa
# 4          4.6          1.5  setosa
# 5          5.0          1.4  setosa
# 6          5.4          1.7  setosa
