R Reverse a Vector

How To Reverse a Vector in R?

We use rev() function to reverse a vector in R programming and pass the vector as argument. This rev() function returns new vector with it’s reversed order of content.

The syntax:

rev(x)

Examples:

m1 <- c(30L, 10L, 45L, 11L)
m2 <- c(30, 10, 45, 11)
m3 <- c("p", "q", "r", "s")

result1 <- rev(m1)
result2 <- rev(m2)
result3 <- rev(m3)
cat("result1:", result1)
cat("result2:", result2)
cat("result3:", result3)

#output:
result1: 11 45 10 30
result2: 11 45 10 30
result3: s r q p

Conclusion:

We use rev() function to reverse a vector in R programming.
