How to Apply the cumprod() Function in R (Example Code)
In this post, I’ll show how to apply the cumprod function in R.
Introduction of Example Data
data(iris) # Load example data 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 |
data(iris) # Load example data 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: How to Use cumprod() Function to Calculate the Cumulative Product of a Data Frame Column
Sepal.Width_cumprod <- cumprod(iris$Sepal.Width) # Compute cumulative products head(Sepal.Width_cumprod) # Return head of cumulative products vector # [1] 3.500 10.500 33.600 104.160 374.976 1462.406 |
Sepal.Width_cumprod <- cumprod(iris$Sepal.Width) # Compute cumulative products head(Sepal.Width_cumprod) # Return head of cumulative products vector # [1] 3.500 10.500 33.600 104.160 374.976 1462.406
