parseMunsell: Parse Munsell Color Notation

In aqp: Algorithms for Quantitative Pedology

Parse Munsell Color Notation

Description

Split Munsell color notation into "hue", "value", and "chroma", with optional conversion to sRGB hex notation, sRGB coordinates, and CIELAB coordinates. Conversion is performed by munsell2rgb.

Usage

parseMunsell(munsellColor, convertColors = TRUE, delim = NA, ...)

Arguments

munsellColor	character vector of Munsell colors (e.g. c('10YR 3/4', '5YR 4/6'))
convertColors	logical, convert colors to sRGB hex notation, sRGB coordinates, CIELAB coordinates
delim	optional, specify the type of delimiter used between value and chroma parts of the Munsell code. By default ":", ",:, "'", and "/" are supported.
...	additional arguments to munsell2rgb

Value

a data.frame object

Examples

# just sRGB
parseMunsell("10YR 3/5", return_triplets = TRUE)

# sRGB + CIELAB (D65 illuminant)
parseMunsell("10YR 3/5", return_triplets = TRUE, returnLAB = TRUE)

# CIELAB only
parseMunsell("10YR 3/5", return_triplets = FALSE, returnLAB = TRUE)

# neutral hue
# note chroma encoded as '0'
parseMunsell('N 3/', convertColors = FALSE)
