How to create a vector with lowercase as well as uppercase letters in R?

R ProgrammingServer Side ProgrammingProgramming

To create a vector with lowercase we can use the word letters and for uppercase the word LETTERS is used in R. If we want to create a vector with both type of letters then both of these words can be combined using c function and if want to create a vector with randomly sampled values of lowercase and uppercase letters then sample function can be used.
