Natural Log and Log of the column in R

Natural Log and Log transformation of the column in R is calculated using log10() and log() function. Let’s see how to calculate

  • Natural Log of the column in R with example
  • Log transformation of the column in R with example

Let’s first create the dataframe

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))
df1

So the resultant dataframe will be

Natural Log and Log of the column in R 1

 

Natural Log of the column in R:

Natural Log transformation of the column in R is calculated using log() function as shown below.

df1[,c(2,3)] <- log(df1[,c(2,3)])
df1

so the resultant natural log transformed data will be

Natural Log and Log of the column in R 2

 

Log of the column in R:

Log transformation of the column in R is calculated using log10() function as shown below.

df1[,c(2,3)] <- log10(df1[,c(2,3)])
df1

so the resultant log transformed data will be

Natural Log and Log of the column in R 3
