fviz_pca_var - Question about contribution units

[kassambara]

email from a factoextra user:

Dear Alboukadel,

I am using your “fviz_pca_var” function and I have one question.

When I do a PCA plot with variables (with function “fviz_pca_var”), and I color it by contribution (“contrib”), I have some variables with a value higher than 100. I thought that this contribution values was in percent (%) unit, but since I am having values higher than 100, I assume that the contribution unit is not percent (%).

Am I right? In which unit are the contribution values?

Best regards,
Bernardo

This is bug and has been fixed now.
(yes the contribution values are in percent)

Thank you for pointing this out!!

Best regards,
A.
