panel.hist: Plot Histograms Flexibly

In metrumrg: Pharmacometric Tools for Data Preparation, Modeling, Simulation, and Reporting

Description

histogram and panel.histogram in package lattice (expected) are univariate. Here, we present a bivariate histogram panel function for use, e.g., with stripplot. panel.bar adds line segments, appropriate for reference lines in a histogram. unitHist calls hist but returns histogram specifications that have been rescaled so that maximum bar height is 1.

Usage

panel.hist(x,y,level,horizontal,col.line,fill,factor,border=col.line,col=fill,
offset=-0.5,font,fontface,...)
panel.bar(x,y,level,horizontal,col,col.line,fill,factor,font,fontface,...)
unitHist(x, plot = FALSE, ...)

Arguments

x	vector
y	vector
level	the level at which to draw the histogram, typically supplied by panel.stratify
horizontal	typically TRUE
col	fill color (ignored for panel.bar)
col.line	border color if border not supplied
fill	fill color if col not supplied
factor	factor by which to expand or attenuate bar heights relative to unity
border	border color
offset	amount to raise the base of each bar relative to the level
...	passed to other functions
font	ignored
fontface	ignored
plot	passed to hist

Value

unitHist returns class histogram with an extra element named ‘heights’. ‘heights’ is proportional to density, but normalized relative to maximum density. Panel functions are used for side effects.
