Function classify::get_equal_interval_breaks

pub fn get_equal_interval_breaks<T: ToPrimitive>(
    num_bins: usize,
    data: &[T]
) -> Vec<f64>

Returns a vector of breaks generated through the Equal Interval Breaks algorithm given the desired number of bins and a dataset

Arguments

• num_bins - The desired number of bins
• data - A reference to a collection of unsorted data points to generate breaks for

Edge cases

• Inputting large u64/i64 data (near their max values) will result in loss of precision because data is being cast to f64
• If there is a wide enoguh gap in the data, this algorithm may produce one or more empty bins

Examples

use classify::get_equal_interval_breaks;

let data: Vec<f32> = vec![0.0, 0.5, 1.0, 1.5, 2.5, 3.0];
let num_bins = 3;

let result: Vec<f64> = get_equal_interval_breaks(num_bins, &data);

assert_eq!(result, vec![1.0, 2.0]);
