clucols {fpc}

Sets of colours and symbols for cluster plotting

Description

clucols gives out a vector of different random colours. clugrey gives out a vector of equidistant grey scales. clusym is a vector of different symbols starting from "1", "2",...

Usage

  clucols(i, seed=NULL)
  clugrey(i,max=0.9)
  clusym

Arguments

i

integer. Length of output vector (number of clusters).

seed

integer. Random seed.

max

between 0 and 1. Maximum grey scale value, see grey (close to 1 is bright).

Value

clucols gives out a vector of different random colours. clugrey gives out a vector of equidistant grey scales. clusym is a vector of different characters starting from "1", "2",...
