would you kindly make an equivalent series in "the french way" but for the case of ICA algorithm, at least geometrically speaking ?
merci

Hi, I have 2 categorical variables in my data for acoustic features from 8 animals. The data has 701 rows for 8 acoustic variables. The two categorical variables are Individual's "ID" and the "experiment" they belonged to. So "ID" has names of the individuals (total 8) and "experiment" has 3 groups - control, drug A and drug B. I wanted to generate an individuals factor map where I could show both categorical variables by different color or shape. Say showing "ID" (the 8 animal) by different colors and showing groups by different shapes. How can I do it in Factominer or factoshiny.
Thanks
