histwidth: Histogram Widths

In exams.forge: Support for Compiling Examination Tasks using the 'exams' Package

Histogram Widths

Description

Creates a set of breaks and absolute frequencies in the range from 'from' to 'to'. The class widths are sampled from widths. The resulting numbers could be multiplied with an integer, if the sum(n) is too small. Additionally, it is checked whether the generated densities are terminating decimals.

Usage

histwidth(from, to, widths, dmax = 100)

width_breaks(from, to, widths, dmax = 100)

dhistwidth(from, to, widths, dmax = 100)

Arguments

from	numeric: start value
to	numeric: end value
widths	numeric: a vector of width to sample from
dmax	numeric: max. denominator value

Value

A list with breaks, n's for each class and decimal if all densities are terminating decimals.

Examples

l <- histwidth(1.6, 2.1, widths=c(0.05, 0.1, 0.15, 0.2))
l
x <- histx(l$breaks, l$n)
histdata(x, l$breaks)
