boxprod: Boxplot per category with respect to a categorical variable...

In SensoMineR: Sensory Data Analysis

Boxplot per category with respect to a categorical variable and a set of quantitative variables

Description

Returns as many boxplots as there are categories for a given categorical variable of interest (in most cases, the product variable). The boxplots are automatically generated for all the quantitative variables (in our type of applications, variables are often sensory descriptors).

Usage

boxprod(donnee, col.p, firstvar, lastvar = ncol(donnee), 
    numr = 2, numc = 2)

Arguments

donnee	a data frame
col.p	the position of the categorical variable of interest
firstvar	the position of the first endogenous variable
lastvar	the position of the last endogenous variable (by default the last column of donnee)
numr	the number of boxplots per row (by default 2)
numc	the number of boxplots per column (by default 2)

Details

Missing values are ignored when forming boxplots.
