Rounding off the column in R can be accomplished by using round() function. In this tutorial we will see how to
- Round off the column to integer
- Round off the column to some decimal places
Let’s first create the dataframe
df1 = data.frame(State = c('Arizona AZ','Georgia GG', 'Newyork NY','Indiana IN','Florida FL'), Score=c(62.345,47.734,55.867,74.256,31.901))
df1
df1 will be
Round off the column to integer
round() function simply round offs the column to integer
df1$Round_off <- round(df1$Score) # Round off the column to integer df1
Rounded off integer will be
Round off the column to decimal places
round() function along with digit arguments rounds off the column to specified decimal places
df1$Round_off <- round(df1$Score ,digit=2) # Round off the column for 2 decimal df1
Rounds off to two decimal places
