How to round values in proportion table in R?

R ProgrammingServer Side ProgrammingProgramming

To round values in proportion table in R, we can first save the proportion table in an object and then use the round function.

For example, if we have a vector say X then we can create a proportion table for data in X using prop.table(table(X)) and store it in an object called Tab and then round the values to two decimal places by using the below given command −

round(Tab,2)

Example 1

Following snippet creates a sample data frame −

x1<-rpois(200,5)
