## Description

The data used here concern a questionnaire on tea. We asked to 300 individuals how they drink tea (18 questions), what are their product's perception (12 questions) and some personal details (4 questions).

## Usage

 `1` ```data(tea) ```

## Format

A data frame with 300 rows and 36 columns. Rows represent the individuals, columns represent the different questions. The first 18 questions are active ones, the 19th is a supplementary quantitative variable (the age) and the last variables are supplementary categorical variables.

## Examples

 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13``` ```## Not run: data(tea) res.mca=MCA(tea,quanti.sup=19,quali.sup=20:36) plot(res.mca,invisible=c("var","quali.sup","quanti.sup"),cex=0.7) plot(res.mca,invisible=c("ind","quali.sup","quanti.sup"),cex=0.8) plot(res.mca,invisible=c("quali.sup","quanti.sup"),cex=0.8) dimdesc(res.mca) plotellipses(res.mca,keepvar=1:4) ## make a hierarchical clustering: click on the tree to define the number of clusters ## HCPC(res.mca) ## End(Not run) ```
