Create Random Sample with Values 0 and 1 in R

It is known that the random sample can be created by using sample function in R. If we want to create a random sample with values 0 and 1 only then there are three different ways to pass them inside the sample function −

• Creating a vector of 0 and 1

• Using 0:1

• Using c(1,2) directly inside the function.

Also, we can set replace argument to TRUE or FALSE based on our requirement.

Examples

 Live Demo

x1<-sample(0:1,size=50,replace=TRUE)
x1

Output

[1] 0 1 1 1 1 0 0 1 0 1 1 0 0 0 1 0 0 1 0 1 1 1 0 0 0 0 0 1 1 1 0 1 0 1 1 0 1 1
