Color a histogram

Description

A histogram with an additional color stripe based on a kernel density estimate.

Usage

heathist(x, breaks = 20, xlab = NULL, ylab = NULL, main = "heathist",
  colpal = "greys", rev = FALSE, simulate = FALSE, daltonize = FALSE,
  cvd = "p", alpha = NULL, nobox = FALSE, add.density = FALSE,
  col.density = "darkred", add.rug = TRUE, col.rug = "black",
  nrcol = 100, ...)

Arguments

x

a numeric vector.

breaks

a numeric value giving the breaks of the histogram.

xlab

x label, standard graphics parameter.

ylab

y label, standard graphics parameter.

main

title(s) of the plot, standard graphics parameter.

colpal

a character vector containing R built-in color names or a name of a LSD colorpalette as a character string (see disco() or disco) (defaults to "heat", if not specified).

rev

logical: if TRUE (FALSE by default), a reversed colorpalette is used.

simulate

logical: if TRUE (FALSE by default), a converted colorpalette is used to simulate dichromat vision according to http://www.daltonize.org (see daltonize).

daltonize

logical: if TRUE (FALSE by default), a converted colorpalette is used to enhance dichromat vision according to http://www.daltonize.org (see daltonize).

cvd

character string implying the type of color vision deficiency ("p" for protanope, "d" for deuteranope or "t" for tritanope).

alpha

alpha value: a two-digit integer between 01 and 99 for color opacity, i.e. appearance of partial or full transparency (usage omitted by default).

nobox

logical: if TRUE (FALSE by default), the box of the plot is omitted.

add.density

if TRUE (FALSE by default), a density line is added to the histogram.

col.density

a R build-in color for the density line (if add.density = TRUE).

add.rug

if TRUE (FALSE by default), a rug (1-d plot of the data) is added below the histogram-bars.

col.rug

a R build-in color for the rug (if add.rug = TRUE).

nrcol

a non-negative integer specifying the number of colors to be used (defaults to 100, if not specified).

...

additional parameters to be passed to points and plot.
