R: Color a barplot.

heatbarplot {LSD}

R Documentation

Color a barplot.

Depict a histogram object as a barplot in a color encoded fashion based on a kernel density estimate.

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

`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.
