How to Apply the formatC() Function in R (2 Examples)

In this article, I’ll explain how to apply the formatC function in R programming.

Creation of Example Data

data(iris)                         # Loading example data
iris_head <- head(iris)
iris_head
#   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 1: Change Decimal Mark Using formatC() Function

formatC(iris_head$Sepal.Length,    # Using formatC function
        decimal.mark = ",")
# [1] "5,1" "4,9" "4,7" "4,6" "5"   "5,4"

Example 2: Specify Width of Character String Using formatC() Function

formatC(iris_head$Sepal.Length,    # Using formatC function
        width = 10)
# [1] "       5.1" "       4.9" "       4.7" "       4.6" "         5"
# [6] "       5.4"
