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 |
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$Sepal.Length, # Using formatC function decimal.mark = ",") # [1] "5,1" "4,9" "4,7" "4,6" "5" "5,4" |
formatC(iris_head$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$Sepal.Length, # Using formatC function width = 10) # [1] " 5.1" " 4.9" " 4.7" " 4.6" " 5" # [6] " 5.4" |
formatC(iris_head$Sepal.Length, # Using formatC function width = 10) # [1] " 5.1" " 4.9" " 4.7" " 4.6" " 5" # [6] " 5.4"
