multi.hist: Multiple histograms with density and normal fits on one page

Description

Given a matrix or data.frame, produce histograms for each variable in a "matrix" form. Include normal fits and density distributions for each plot.

The number of rows and columns may be specified, or calculated.

May be used for single variables.

Usage

multi.hist(x,nrow=NULL,ncol=NULL,density=TRUE,freq=FALSE,bcol="white",
      dcol=c("black","black"),dlty=c("dashed","dotted"),
      main="Histogram, Density, and Normal Fit",...)

Arguments

x
matrix or data.frame
nrow
number of rows in the plot
ncol
number of columns in the plot
density
density=TRUE, show the normal fits and density distributions
freq
freq=FALSE shows probability densities and density distribution, freq=TRUE shows frequencies
bcol
Color for the bars
dcol
The color(s) for the normal and the density fits. Defaults to black.
dlty
The line type (lty) of the normal and density fits. (specify the optional graphic parameter lwd to change the line size)
main
title for each panel
...
additional graphic parameters (e.g., col)

Examples

Run this code
multi.hist(sat.act) 
multi.hist(sat.act,bcol="red")
multi.hist(sat.act,dcol="blue")  #make both lines blue
multi.hist(sat.act,dcol= c("blue","red"),dlty=c("dotted", "solid")) 
multi.hist(sat.act,freq=TRUE)   #show the frequency plot
multi.hist(sat.act,nrow=2)
