Fisher's natural breaks classification
Description
The function provides an interface to finding class intervals
for continuous numerical variables, for example for choosing colours for
plotting maps.
Usage
fisher(vec, n = 7, diglab = 2)
Arguments
vec
a continuous numerical variable
n
number of classes required (n = 7 is default)
diglab
number of digits (n = 2 is default)
Details
The "fisher" style uses the algorithm proposed by W. D. Fisher
(1958) and discussed by Slocum et al. (2005) as the Fisher-Jenks algorithm.
This function is adopted from the classInt package.
Value
Vector with clustering
