Munsell hues are arranged on the unit circle with "neutral" at the center.
huePositionCircle(
hues = huePosition(returnHues = TRUE),
value = 6,
chroma = 10,
chip.cex = 5.5,
label.cex = 0.66,
seg.adj = 0.8,
seg.col = grey(0.4),
plot = TRUE,
simulateCVD = NULL,
CVDseverity = 1
)Arguments
- hues
vector of Munsell hues, commonly derived from
huePosition()- value
single integer, Munsell value used to create an actual color
- chroma
single integer, Munsell chroma used to create an actual color
- chip.cex
numeric, scaling for color chips
- label.cex
numeric, scaling labels
- seg.adj
numeric, scaling for line segment cues
- seg.col
single color, color used for line segment cues
- plot
logical, generate output on the current graphics device
- simulateCVD
simulate color vision deficiencies with the colorspace package, should be the character representation of a function name, one of: 'deutan', 'protan', or 'tritan'.
- CVDseverity
numeric value between 0 (none) and 1 (total), describing the severity of the color vision deficiency
Value
an invisible data.frame of data used to create the figure
Note
The best results are obtained when setting margins to zero, and inverting foreground / background colors. For example: par(mar = c(0, 0, 0, 0), fg = 'white', bg = 'black').

Examples
# keep examples from using more than 2 cores
data.table::setDTthreads(Sys.getenv("OMP_THREAD_LIMIT", unset = 2))
# better graphics defaults
op <- par(
mar = c(0, 0, 0, 0),
fg = 'white',
bg = 'black',
xpd = NA
)
# full set of hues, as generated by huePosition(returnHues = TRUE)
huePositionCircle()
# just a few hues
huePositionCircle(hues = c('5R', '5Y', '5G', '5B', '5P'))
# adjust Munsell value and chroma
huePositionCircle(value = 3, chroma = 6)
# reset graphics state
par(op)
