R: Histogram for each descriptor

histprod

R Documentation

Histogram for each descriptor

Description

Computes automatically histograms for a set of quantitative variables.

Usage

histprod(donnee, firstvar, lastvar = ncol(donnee), numr = 2, 
    numc = 2, adjust = 1)

Arguments

`donnee`	a data frame
`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 histograms per row (by default 2)
`numc`	the number of histograms per column (by default 2)
`adjust`	the bandwidth used is actually 'adjust*bw'. This makes it easy to specify values like "half the default" bandwidth.

Details

Displays histograms with a common Y-axis as well as the local estimator of the density for each descriptor, hence the adjust parameter to fill in. Displays also the normal distribution with mean and variance the respective values estimated for each descriptor.
