upper {wakefield}

Generate Random Letter Vector

Description

upper - Generates a random character vector of upper case letters.

lower - Generates a random character vector of lower case letters.

upper_factor - Generates a random factor vector of upper case letters.

lower_factor - Generates a random factor vector of lower case letters.

Usage

upper(n, k = 5, x = LETTERS, prob = NULL, name = "Upper")

lower(
  n,
  k = 5,
  x = c("a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p",
    "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"),
  prob = NULL,
  name = "Lower"
)

upper_factor(n, k = 5, x = LETTERS, prob = NULL, name = "Upper")

lower_factor(
  n,
  k = 5,
  x = c("a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p",
    "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"),
  prob = NULL,
  name = "Lower"
)

Arguments

n

The number elements to generate. This can be globally set within the environment of r_data_frame or r_list.

k

The number of the elements of x to sample from (uses 1:k).

x

A vector of elements to chose from.

prob

A vector of probabilities to chose from.

name

The name to assign to the output vector's varname attribute. This is used to auto assign names to the column/vector name when used inside of r_data_frame or r_list.

Value

Returns a random character/factor vector of letter elements.
