How to replace one vector elements with another vector elements in R?

If the data is incorrectly recorded then we need to replace that with the correct. One such case could be reading a vector with values that belong to another vector. In this type of situation, we should replace the vectors appropriate. In R, it can be easily done by using <- operator.

Example

 Live Demo

x1<-1:10
x1

Output

[1] 1 2 3 4 5 6 7 8 9 10

Example

 Live Demo

y1<-c(5,15,20,25,30,35,40,45,50,55)
y1

Output

[1] 5 15 20 25 30 35 40 45 50 55

Replacing x1 with y1 values

Example

x1<-y1
x1

Output

[1] 5 15 20 25 30 35 40 45 50 55

Example

x2<-sample(0:5,120,replace=TRUE)
