r_list: List Production (From Variable Functions)

In wakefield: Generate Random Data Sets

Description

Produce a named list that allows the user to lazily pass unnamed wakefield variable functions (optionally, without call parenthesis).

Usage

r_list(n, ..., rep.sep = "_")

Arguments

n	The length to pass to the randomly generated vectors.
rep.sep	A separator to use for repeated variable names. For example if the age is used three times (r_list(age, age, age)), the name "Age" will be assigned to all three vectors in the list. The results in column names c("Age_1", "Age_2", "Age_3"). To turn of this behavior use rep.sep = NULL. This results in c("Age", "Age", "Age") for vector names, leading to c("Age", "Age.1", "Age.2") if coerced to a data.frame.
...	A set of optionally named arguments. Using wakefield variable functions require no name or call parenthesis.

Value

Returns a named list of equal length vectors.
