Example
# A code to illustrate the rev() function in R# Creating a vector objectda <- c(1, 5, 6, 7, 33, 2, 9)b <- c(1:10)# reversing the elements of the vectorrev(a)rev(b)
Explanation
- Line 3–4: We create vector objects,
aandb. - Line 8–9: We call the
rev()function to reverse the elements inaandb.
