soilPalette: Soil Color Palette

In aqp: Algorithms for Quantitative Pedology

Soil Color Palette

Description

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

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)
