legendright: Plot multivariate data into colour channels

Description

plot graph with legend right of it

plot multivariate data into colour channels using geom_tile

normalize.colrange normalizes the range of each column to [0, 1]

normalize.range normalizes the range of all columns to [0, 1]

normalize.minmax normalizes the range of each column j to [min_j, max_j]

legends for mixed colour plots

multi channel colour mixing

Usage

legendright(p, l, legend.width = 8,
    legend.unit = "lines")
  qmixtile(object,
    purecol = stop("pure component colors needed."),
    mapping = aes_string(x = "x", y = "y", fill = "spc"),
    ..., map.tileonly = FALSE)
  normalize.colrange(x, na.rm = TRUE, legend = FALSE,
    n = 100)
  normalize.range(x, na.rm = TRUE, legend = FALSE, n = 100)
  normalize.minmax(x, min = 0, max = 1, legend = FALSE,
    n = 100)
  qmixlegend(x, purecol, dx = 0.33, ny = 100,
    labels = names(purecol),
    normalize = normalize.colrange, ...)
  colmix.rgb(x, purecol, against = 1, sub = TRUE,
    normalize = normalize.colrange, ...)

Arguments

p

plot object

l

legend object

legend.width,legend.unit

size of legend part

object

matrix to be plotted with mixed colour channels

purecol

pure component colours, names determine legend labels

mapping

see geom_tile

...

qmixtile: handed to colmix.rgb

qmixlegend: handed to normalize

colmix.rgb: handed to normalize

map.tileonly

if TRUE, mapping will be handed to geom_tile instead of ggplot.

na.rm

see link[base]{min}

legend

should a legend be produced instead of normalized values?

n

of colours to produce in legend

min

numeric with value corresponding to "lowest" colour for each column

max

numeric with value corresponding to "hightest" colour for each column

dx

width of label bar

ny

number of colours in legend

labels

component names

x

matrix with component intensities in columns

against

value to mix against (for sub = TRUE only, 1 = white, 0 = black)

sub

subtractive color mixing?

normalize

function to normalize the values.

Value

• invisible NULL

  list with components ymin, max and fill to specify value and fill colour value (still numeric!) for the legend, otherwise the normalized values

  ggplot object with legend

  character with colours
