How to visualize 3 factors using geom_point?
How to visualize 3 factors using geom_point?
I have 3 factors that I would like to represent on an NMDS plot.
my first attempt is this:
However, I would like the circles (or triangles) to be filled, or empty based on if they are Fungi or NF)
ggplot(data=NMDS2_plsMet,aes(x,y,colour=Location))+
geom_point(aes(shape=Insect,fill=Fungi))+theme_bw()
So then I tried this:
ggplot(data=NMDS2_plsMet,aes(x,y,colour=Location))+
geom_point(aes(shape=Insect,fill=Fungi))+
scale_shape_manual(values=shape_values)+theme_bw()
Any suggestions for how I can have filled/empty circles and triangles.
You might need to use both
scale_fill_manual and scale_size_manual (scale_size_manual will need both Insect and Fungi, and may be needed to select shapes that are hollow). For scale_fill_manual, try something akin to +scale_fill_manual(name = "Type", labels = c("Fungi", "NF"), values = c()) sthda.com/english/wiki/…– A Duv

some of the shapes (21-25 I think) take a fill as well as a colour.
