Here are 100 one-liners in R covering various operations:

1. Print “Hello, World!”:

cat("Hello, World!\n")

2. Generate a sequence from 1 to 10:

1:10

3. Calculate the sum of numbers from 1 to 10:

sum(1:10)

4. Create a vector of 5 random numbers between 0 and 1:

runif(5)

5. Define a vector: v with values 1, 2, 3, 4, 5:

v <- c(1, 2, 3, 4, 5)

6. Check the length of vector v:

length(v)

7. Access the third element of vector v:

v[3]

8. Add 1 to each element of vector v:

v + 1

9. Multiply each element of vector v by 2:

v * 2

10. Find the mean of vector v:

mean(v)

11. Create a matrix with 3 rows and…
