Dear Thiago,
I don't know the type and values of your data, but let's say that
endemism_values is a numeric vector containing positive integers.
In this case you can use this formula to produce the desired colors:
heat.colors(max(endemism_values))[endemism_values]
So this should work:
symbols(coords, bg =heat.colors(max(endemism_values))[endemism_values],
circles=endemism_values, inches = .5, add = T)

Hi Erin,
Thanks for you response.
I tried it but, fg gives colors to a symbols border and bg fill it with
colors.
The thing is, while the circles gives a radius to symbols proportionally to
the endemism values (I checked and it's correct), the fg or bg don't seems
to correctly follows the values.
And this is where I'm stuck. Any other ideias??
Cheers,
T.

Hi Thiago,
Did you try using fg instead or fg with bg? Looks like in the R docs that
the color for the symbol is fg.

Hi Folks,
I'm trying to plotting endemism data into a map, and I would like take the
symbol color for each sample follow a gradient of endemism values for this
sample, like a heat map, then higher values would results in reddish
colors
and lower values to yellowish colors. I tried several variation in the
code, changing colors and values structure, but is not working so far. Any
ideas??
R code:
map("world", col="black", fill=F)
> symbols(coords, bg =heat.colors(endemism_values), circles=
endemism_values, inches = .5, add = T)
Thanks
