hmColors: Set d3heatmap color options

In rstudio/d3heatmap: Interactive Heat Maps Using 'htmlwidgets' and 'D3.js'

Set d3heatmap color options

Description

Set and adjust the colors and color options for the d3heatmap

Usage

hmColors(
  d3heatmap,
  theme = c("", "dark"),
  colors,
  range,
  color.bins,
  symmetrical,
  na.color
)

Arguments

d3heatmap	Required A valid d3heatmap object
theme	A custom CSS theme to use. Currently the only valid values are "" and "dark". "dark" is primarily intended for standalone visualizations, not R Markdown or Shiny.
colors	Either a colorbrewer2.org palette name (e.g. "YlOrRd" or "Blues"), or a vector of colors to interpolate in hexadecimal "#RRGGBB" format, or a color interpolation function like colorRamp.
range	A vector of two numbers, namely the minimum and maximum value to use when determining the mapping from values to colors. This is useful when the range of values changes between heatmaps, but colors should be the same (optional, defaults to the minimum and maximum of x).
color.bins	numeric The number of colors to generate from the palette, or the breakpoints between the bins
symmetrical	logical Arrange color bins symmetrically around zero?
na.color	Color of NA values in heatmap. Defaults to neutral gray.

Value

Modified d3heatmap object
