The palette parameter in fviz_pca_biplot function (from factoextra package) can't change the colors. I have added habillage parameter, and function works correctly, except colors. Is this a bug, or I don't understand the function? The same parameter works perfectly with fviz_pca_ind.

Hi, can you elaborate on what you would you like to be colored? In both fviz_pca_biplot and fviz_pca_ind, the observations are colored with the habillage parameter. – StupidWolf Dec 26 '19 at 00:10

Tried the grey palette. Habillage parameter works excellent, but the colors doesn't appeal to me. Eventually, I figure out with `+ scale_color_grey()` since fviz_pca_biplot relies on ggplot. Thanks – IP-84 Dec 27 '19 at 01:24
