darkColors {oligo} | R Documentation

## Create set of colors, interpolating through a set of preferred colors.

### Description

Create set of colors, interpolating through a set of preferred colors.

### Usage

    darkColors(n)
    seqColors(n)
    seqColors2(n)
    divColors(n)

### Arguments

`n` | integer determining number of colors to be generated

### Details

`darkColors` is based on the Dark2 palette in RColorBrewer, therefore useful to describe qualitative features of the data.

`seqColors` is based on Blues and generates a gradient of blues, therefore useful to describe quantitative features of the data. `seqColors2` behaves similarly, but it is based on OrRd (white-orange-red).

`divColors` is based on the RdBu pallete in RColorBrewer, therefore useful to describe quantitative features ranging on two extremes.

### Examples

    x <- 1:10
    y <- 1:10
    cols1 <- darkColors(10)
    cols2 <- seqColors(10)
    cols3 <- divColors(10)
    cols4 <- seqColors2(10)
    plot(x, y, col=cols1, xlim=c(1, 13), pch=19, cex=3)
    points(x+1, y, col=cols2, pch=19, cex=3)
    points(x+2, y, col=cols3, pch=19, cex=3)
    points(x+3, y, col=cols4, pch=19, cex=3)
    abline(0, 1, lty=2)
    abline(-1, 1, lty=2)
    abline(-2, 1, lty=2)
    abline(-3, 1, lty=2)
