densitylane {LSD}

Visualize a density in a rectangular fashion

Description

Add a color stripe to an existing plot based on a kernel density estimate.

Usage

densitylane(
  x,
  y,
  pos = 1,
  width = 0.4,
  colpal = "standard",
  rev = FALSE,
  simulate = FALSE,
  daltonize = FALSE,
  cvd = "p",
  alpha = NULL,
  horizontal = horizontal,
  nrcol = 75
)

Arguments

x

density$x values of a density object.

y

density$y values of a density object.

pos

the x co-ordinate of the lane (mid point).

width

a numeric value giving the width of the lane.

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).

horizontal

logical: if TRUE (FALSE by default), rotation of 90 degrees is applied.

nrcol

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