Hi John,
As heat.colors is a function that returns a vector of colors specified
by the "n" argument, you could write something like this:
my_custom_colors<-function(n,color_vector="lightgray")
return(rep(color_vector,length.out=n)))
and then pass the desired color vector to it:
green_n_black<-c("green", "green", "black",
"green", "green", "black", "black", "green", "green", "black")
my_custom_colors(12,green_n_black)
my_custom_colors(4,green_n_black)
