Calculate Correlation of One Data Frame Column to All Others in R (Example Code)

In this article you’ll learn how to compute the correlation of one data frame column to all the others in R.

Creation of Example Data

data(iris)                   # Example data
iris_new <- iris[ , c(1:4)]
head(iris_new)
#   Sepal.Length Sepal.Width Petal.Length Petal.Width
# 1          5.1         3.5          1.4         0.2
# 2          4.9         3.0          1.4         0.2
# 3          4.7         3.2          1.3         0.2
# 4          4.6         3.1          1.5         0.2
# 5          5.0         3.6          1.4         0.2
# 6          5.4         3.9          1.7         0.4

Example: Applying cor() Function Get Correlations of One Column with All Others

cor(iris_new[ , - 1],        # Get correlation estimates
    iris_new$Sepal.Length)
#                    [,1]
# Sepal.Width  -0.1175698
# Petal.Length  0.8717538
# Petal.Width   0.8179411
