Matlab-Like Color Palettes

Source: R/matlab.palette.R

Two palettes going from blue over green to red, approximately as the standard palette of Matlab does. The second one has darker green values and is better suited for plotting lines on white background.

matlab.palette(n = 100, ...)

matlab.dark.palette(n = 100, ...)

alois.palette(n = 100, ...)

Arguments

n

the number of colors to be in the palette.
...

further arguments are handed to grDevices::rainbow() (alois.palette: grDevices::colorRampPalette()).

Value

A vector containing the color values in the form "#rrbbggaa".

Examples

# Matlab dark palette

op <- par(mar = c(0, 0, 0, 0))
pie(rep(1, 12), col = matlab.palette(12))
par(op)

plot(flu, col = matlab.palette(nrow(flu)))

plotmap(faux_cell[, , 1200], col.regions = matlab.palette())

# Matlab dark palette

op <- par(mar = c(0, 0, 0, 0))
pie(rep(1, 12), col = matlab.dark.palette(12))
par(op)

plot(flu, col = matlab.dark.palette(nrow(flu)))

plotmap(faux_cell[, , 1200], col.regions = matlab.dark.palette())

# Alois palette

op <- par(mar = c(0, 0, 0, 0))
pie(rep(1, 12), col = alois.palette(12))
par(op)

plot(flu, col = alois.palette(nrow(flu)))

plotmap(faux_cell[, , 1200], col.regions = alois.palette())
