level: Generate Random Vector of Levels

In wakefield: Generate Random Data Sets

Description

level - Generate a random vector of integer levels (1-4).

math - Generate a random vector of integer mathematics levels (1-4) similar to New York State grades 3-8 assessment results.

ela - Generate a random vector of integer English language arts (ELA) levels (1-4) similar to New York State grades 3-8 assessment results.

Usage

level(n, x = 1:4, prob = NULL, name = "Level")

math(n, x = 1:4, prob = c(0.29829, 0.33332, 0.22797, 0.14042), name = "Math")

ela(n, x = 1:4, prob = c(0.3161, 0.37257, 0.2233, 0.08803), name = "ELA")

Arguments

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

Details

Distribution of levels (used in prob) were taken from New York State' s 2014 assessment report: http://www.p12.nysed.gov/irs/

Level	ELA	Math
1	31.6%	29.8%
2	37.3%	33.3%
