histwidth

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 is checked if the densities generated are terminating decimals.

Usage

histwidth(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)
