Relating sensory and instrumental data

The cap function uses one data set with instrumental measures and/or QDA data and one data set with hedonic judgements.

It projects panelists according to their preference and adds the products'characteristics.
Moreover, correlation coefficients between hedonic judgements and each instrumental or descriptor variable are calculated and, for each variable, a graph is displayed with the mean point of the variable and the panelists coloured according to their correlation coefficient.
