  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",

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.
