Soil Color Palette — soilPalette • aqp

A very simple function for generating labeled swatches of soil colors. Largely based on colorspace::swatchplot.

Usage

soilPalette(
  colors,
  lab = colors,
  lab.cex = 0.75,
  dynamic.labels = TRUE,
  x.inset = 0.01,
  y.inset = 0.01,
  ...
)

Arguments

colors: vector of hex colors (e.g. #A66E46FF)
lab: vector of labels
lab.cex: character scaling for labels
dynamic.labels: logical, adjust label colors for maximum contrast via invertLabelColor
x.inset: horizontal adjustment for labels
y.inset: vertical adjustment for labels
...: further arguments to colorspace::swatchplot

Value

nothing is returned, function called for graphic output

Note

The result is a simple figure on the active plotting device.

Examples


# maybe useful for teaching about soil color

par(mfrow=c(2,1), mar=c(1,1,1,1))

# demonstrate range of Munsell value
m <- sprintf('10YR %s/4', 2:8)
# convert to hex representation
cols <- parseMunsell(m)
# plot
soilPalette(cols, m)

# demonstrate range of Munsell chroma
m <- sprintf('10YR 4/%s', 2:8)
# convert to hex representation
cols <- parseMunsell(m)
# plot
soilPalette(cols, m)
