Geometric Mean in R (Geometric mean of column in R)

Geometric mean of the column in R is calculated using geometric.mean() function of the psych package. Let’s see how to calculate the Geometric mean of the dataframe in R and Geometric mean of the vector with an example of each.

Let’s first create the dataframe

install.packages("psych")
library(psych)

df1 = data.frame(Name = c('George','Andrea', 'Micheal','Maggie','Ravi','Xien','Jalpa'), 
                 Mathematics_score=c(45,78,44,89,66,49,72),
                 Science_score=c(56,52,45,88,33,90,47))

So the resultant dataframe will be

Geometric Mean in R 1 Geometric mean of the column in R 1

 

Geometric mean of the column in R:

Geometric mean of the Mathematics_score is calculated as shown below

geometric.mean(df1$Mathematics_score,na.rm=TRUE)

So the Geometric mean of the column will be

[1] 61.15899

 

 

Geometric mean of the vector in R:

vector1 <- c(50,47,45,89,66,49,72)  # create vector
geometric.mean(vector1,na.rm=TRUE)  

So the Geometric mean of the vector will be

[1] 57.93797
