heatbarplot(x, colpal = "heat", simulate = FALSE, daltonize = FALSE,
  cvd = "p", alpha = NULL, rev = FALSE, horizontal = FALSE,
  nrcol = 100, ...)

Arguments

x

a histogram object.

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).

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).

rev

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

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).

...

additional parameters to be passed to points and plot.
