Hello,
This is my first time posting to the r-help mailing list and I'm a
relative amateur using R, so forgive my naivety. I am constructing a
ternary diagram using the ggtern extension of the ggplot package, and I'm
having some trouble with the colour gradient I want it to display. I have
attached the output plot, where a rainbow colour gradient can be seen, but
I really need these colours to be in reverse order. This is the command I
used to construct the plot;
#Plot construction
ggtern(data= C27_C29_C31, aes(x=C27,y=C29,z=C31))+geom_point(aes(colour=
GST),size=3)+theme_light()+theme_nogrid_minor()+scale_colour_gradientn(colours
= rainbow(5.5))
Is there a simple way to reverse the colours in the scale_colour_gradientn
command?
Kind regards,
Jake Andrae
