In dimRed: A Framework for Dimensionality Reduction

Mixing color ramps

Description

mix different color ramps

Usage

mixColorRamps(vars, ramps)

mixColor1Ramps(vars, ramps = colorRamp(c("blue", "black", "red")))

mixColor2Ramps(
  vars,
  ramps = list(colorRamp(c("blue", "green")), colorRamp(c("blue", "red")))
)

mixColor3Ramps(
  vars,
  ramps = list(colorRamp(c("#001A00", "#00E600")), colorRamp(c("#00001A", "#0000E6")),
    colorRamp(c("#1A0000", "#E60000")))
)

Arguments

vars	a list of variables
ramps	a list of color ramps, one for each variable.

Details

automatically create colors to represent a varying number of dimensions.

Examples

cols <- expand.grid(x = seq(0, 1, length.out = 10),
                    y = seq(0, 1, length.out = 10),
                    z = seq(0, 1, length.out = 10))
mixed <- mixColor3Ramps(cols)

## Not run: 
if(requireNamespace("rgl", quietly = TRUE)) {
rgl::plot3d(cols$x, cols$y, cols$z, col = mixed, pch = 15)
}

cols <- expand.grid(x = seq(0, 1, length.out = 10),
                    y = seq(0, 1, length.out = 10))
mixed <- mixColor2Ramps(cols)

if(requireNamespace("graphics", quietly = TRUE)) {
plot(cols$x, cols$y, col = mixed, pch = 15)
}
