merge two arrays together in R

arr1 <- c(1,2,3,4)
arr2 <- c(5,6,7,8) 
combined <- c(arr1,arr2)

This code creates two arrays, arr1 and arr2, and assigns values to them. The third line uses the c() function which combines the two arrays, arr1 and arr2, into a single array, combined. The output of this code is a combined array with all the values from arr1 and arr2.
