colour.scheme: internal function for node colour scheme

Description

This function is called during network representations to set node colours. If the number of colours defined by user do not match with the number of elements, the algorithm provide a default set of colours.

Usage

colour.scheme(def=NA, N=NA, colors=c("green2","red","yellow","blue","DarkOrchid1",
"gray51","chocolate","cyan4","saddle brown","aquamarine","chartreuse","chocolate1",
"DarkOrchid3","gray18","gold","DarkOrchid4","green4","gray29", "sienna3","tan1","blue4",
"limegreen","gray73","bisque3","deeppink","red4","OliveDrab4","gray95", "salmon",
"DeepPink4","green yellow","gray4","hot pink","pink2","dark orange","gold3"))

Arguments

def

a vector containing the set of colours defined by user

N

a numeric representing the number of elements to be coloured

colors

a vector with default colours to be used if 'def' is different from 'N'

Value

a vector of strings representing 'N' colours

Details

If the number of elements is higher than the number of colours (35 by default), colours are randomly selected.

Examples

colour.scheme(def=c("blue","red"),N=4)
Colors<-colour.scheme(def=c("blue","red"),N=4,colors=c("black","gray33","gray66","orange","red"))
plot(c(1:4),col=Colors,pch=16)

#Given 10 individuals classified into three groups,
#this will provide the colour for each individual:
group<-c(1,1,1,2,2,2,1,2,3,3) # defines los grupos
colour.scheme(N=length(unique(group)))[group]
