# triangle.design: Construct a design for triangle tests In SensoMineR: Sensory Data Analysis

## Description

Construct a design to make triangle tests.

## Usage

 ```1 2``` ```triangle.design (nbprod , nbpanelist, bypanelist = nbprod*(nbprod-1)/2, labprod=1:nbprod, labpanelist=1:nbpanelist) ```

## Arguments

 `nbprod` number of products to compare `nbpanelist` number of panelists who make the triangle test `bypanelist` number of expermient that each panelist can done (by default each panelist make all the comparisons between the products `labprod` name of the products (by default, the product are coded from 1 to the number of products `labpanelist` name of the panelists (by default, the panelists are coded from 1 to the number of panelists

## Details

Triangle test: panelists receive three coded samples. They are told that two of the sample are the same and one is different. Panelists are asked to identify the odd sample.

## Value

Returns an data.frame of dimension (t,3), where t is the number of experiments. In column 1, 2 and 3 the product to test are given. The product in column 1 is by coded "X", in column 2 is coded by "Y" and in column 3 is coded by "Z". Panelist should start by product "X", then "Y" and then by "Z".
