Subject: Re: [R] Colorizing different individuals with fviz
Hi Mahmood,
After scanning the replies and finding the "factoextra" and
"FactoMineR" packages I can say with confidence that the col= argument
won't work. First, the graphic output if via ggplot, and I don't think
that "col=" is a valid argument in that environment.
You seem to be using an object that is a list of matrices. Whether
there is a value in there that will separate your individuals into the
"red" and "black" groups I do not know.
I think that Bill is right, you will have to fall back on something like:
col.ind=c(rep("black",10),rep("red",10))
Jim
