can't color code circles without them changing to squares & triangles

[raynamharris]

Hi,

I love this package! But, I would like to be able to use habillage to color code my data without changing the circles to squares, triangles, and crosses. How can I do that?

Thanks,
Rayna

Hi,

I updated now factoextra on Github. A New argument pointshape has been added in fviz_pca(). When you use habillage, point shapes change automatically by groups. To avoid this behaviour use for example pointshape = 19 in combination with habillage.

Note that, now factoextra depends on ggpubr for plotting. Install the latest version on Github as follow:

# Install the latest version of factoextra
if(!require(devtools)) install.packages("devtools")
devtools::install_github("kassambara/factoextra")

# Install the latest version of ggpubr
devtools::install_github("kassambara/ggpubr")

Please try the following R code and let me know if it works for you:

library(factoextra
data(iris)
res.pca <- prcomp(iris[, -5],  scale = TRUE)
fviz_pca_ind(res.pca, habillage = iris$Species, addEllipses = TRUE, pointshape = 19)

Have a great day!!

I have a small comment. The new option pointshape is very nice.
However, it seems that the bottom right part of the colored text (a) appear behind the points in the legend keys.

Would it be possible to set show.legend = FALSE for the geom_text()?

[kassambara]

fixed now! Please install the latest version of factoextra and use the argument show.legend.text = FALSE. It should work...

wonderful thanks!!
