histx: histx

In sigbertklinke/exams2moodle: Access routines to XML Moodle files and helper routines to simplify generating exercises for Moodle from the 'exams' package

histx

Description

Given the breaks and the number of observations a data set is generated with stats::runif() using the class mids: x_i = class\_mid_j + alpha*class\_width_j/2. The default alpha=0.99 ensures that generated observations do not lie on the class borders.

Usage

histx(breaks, n, alpha = 0.99)

Arguments

breaks	numeric: class borders
n	numeric: number of observations in each class
alpha	numeric: how far the generated observations can be away from the class mids (default: 0.99)

Value

the generated data set

Examples

q  <- sort(sample(seq(0.1, 0.9, by=0.1), 4))
qx <- pnorm(q)
histx(qx, diff(q))
