Details

If you want to display supplementary individuals or variables and you're using the dudi.coa function, you can add the coordinates of suprow and/or supcol to as supr and/or supr elements added to your dudi.coa result (See example).

If you want to display supplementary individuals or variables and you're using the dudi.acm function, you can add the coordinates of suprow and/or supcol to as supi and/or supv elements added to your dudi.acm result (See example).

If you want to display supplementary individuals or variables and you're using the dudi.pca function, you can add the coordinates of suprow and/or supcol to as supi and/or supv elements added to your dudi.pca result (See example).
