Hello,
I am quite a begginner with ggplot and partners, so I apologize if the question is very basic.
I'd like to use fviz_pca_biplot to plot results from a PCA but I can't manage to set parameters as wanted.
Here is what I am coding:
fviz_pca_biplot(correlatives.pca,
repel=TRUE,
# Individuals
geom.ind = "point",
fill.ind = habillage$g_sp,
pointshape = 21 ,
pointsize = 2,
alpha.ind=0.4,
# Variables
alpha.var =1,
col.var = "contrib",
legend.title = list(fill = "Species", color = "Contrib"))
And what I get:
It is almost what I want except I'd like to remove strokes of points, and mean group points.
Any idea?
Thanks all.
