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,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

main

title for each panel

...

additional graphic parameters (e.g., col)

Examples

multi.hist(sat.act) 
multi.hist(sat.act,col="red")
multi.hist(sat.act,freq=TRUE)   #show the frequency plot
multi.hist(sat.act,nrow=2)
