In R factoextra ,the result of 'fviz_ellipses' and 'facto

When using function 'fviz_ellipses' from 'factoextra' package ,it show variable 'Age' and 'Time' is the top 2 variables which have huge influence for Dim1/Dim2,but 'Age' and 'Time' not in the result of 'facto_summarize'. Anyone can help to clear this ? or I misunderstanding something. Thanks

library(tidyverse)
library(factoextra)
library(FactoMineR)
res.mca <- MCA(poison,quanti.sup = 1:2,
               quali.sup=3:4,
              graph=FALSE)



fviz_ellipses(res.mca,1:2,geom="point")

facto_summarize(res.mca,'var',axes=1:2) %>% filter(name %in% c('Age','Time') )

i have addition question :when using 'facto_summarize(res.mca,'var',axes=1:2)' ,it show the content of original data not the variable name ,how can it show variable names? thanks

CodePudding user response：

Since you specify the first two variables as supplementary quantitative vars, you will get their results by accessing the corresponding result 'quanti.sup':

facto_summarize(res.mca,'quanti.sup',axes=1:2) %>% filter(name %in% c('Age','Time') )

Returns:

     name       Dim 1       Dim 2       Dim 3       Dim 4      Dim 5
