qplotmix: Plot multivariate data into colour channels

In hyperSpec: Work with Hyperspectral Data, i.e. Spectra + Meta Information (Spatial, Time, Concentration, ...)

Plot multivariate data into colour channels

Description

plot graph with legend right of it

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.null(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 and colmix.rgb hand further arguments to the normalize function
map.tileonly	if TRUE, mapping will be handed to geom_tile instead of ggplot.
x	matrix with component intensities in columns
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
normalize	function to normalize the values.
against	value to mix against (for sub = TRUE only, 1 = white, 0 = black)
sub	subtractive color mixing?

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
