R help - Oct 2019 - Change colour ggiNEXT plot package iNEXT

I thought it was a major package for ecological analysis. Anyway,
thank you for the tips. I'll dip from there.

Yours is the first question in 20 years of Rhelp about the package iNEXT.

Apparently, the iNEXT package was first described in an academic paper
published in 2016, although CRAN archives go back to 2015.
http://chao.stat.nthu.edu.tw/wordpress/paper/120_pdf_appendix.pdf
https://cran.r-project.org/src/contrib/Archive/iNEXT/

The vignette below has a section entitled "General Customization"
which talks about color. See the four lines of code I've added to the
vignette's code to get a general idea what to do.
https://cran.r-project.org/web/packages/iNEXT/vignettes/Introduction.html

library(iNEXT)
library(ggplot2)
library(gridExtra)
library(grid)
data("spider")
out <- iNEXT(spider, q=0, datatype="abundance")
g <- ggiNEXT(out, type=1, color.var = "site")
print(g)
g1 <- g + scale_colour_manual(values=c("yellow",
"green"))
print(g1)
g2 <- g1 + scale_fill_manual(values=c("yellow", "green"))
print(g2)
